The Secrets to Creating a Killer Cast for Your Mystery

Here’s one of the first secrets unlocked for a mystery novel: There are mandatory
characters you need to set your mystery in motion.
The Mandatory Mystery Crew
You can’t have a mystery without a crime, and you can’t have a crime without the core
cast. These characters form the required foundation of your story:

  • Victim: Without a victim, there is no crime. They may or may not be dead when
  • the story begins.
  • Sleuth: The character who investigates the crime: your professional or amateur
  • detective.
  • Multiple Suspects: You need more than one character who could have done it. At least a few of these need to have the opportunity to commit the crime. Otherwise, the mystery is solved too quickly.
  • Motive: Each suspect must have a reason why they are a suspect.
  • Culprit (Antagonist): The character

Once you have your mandatory characters, you can fill out the rest of your cast with supporting players, such as a sidekick, a mentor, multiple victims or antagonists, experts, or characters who provide local color.

The Protagonist Rule: Why One is the Magic Number

One of the most fundamental principles we stress is this: A story can only have one protagonist.

This isn’t just an arbitrary rule; it’s about engaging the reader. The protagonist is the central character whose journey the reader follows and whose goal drives the entire plot. Readers need a single entity to connect with and root for. If they don’t know who to cheer for, they’re likely to lose interest.To help writers focus their energy, we identified three types of protagonists:

  • Single Protagonist: The most straightforward, where one main character drives the plot toward a clear goal.
  • Combined Protagonist: Two main characters who share the exact same story goal and stakes. If an event helps one, it helps the other; if it hurts one, it hurts the other. They must have distinct personalities to create necessary friction.
  • Group Protagonist: Three or more characters who work together to achieve the central story goal (like a heist team or a community). While individual characters may experience events differently, the group as a whole is either moving closer to or farther away from the main goal.

Defining this pivotal character is the first step in crafting an effective skeleton blurb for your mystery. For those of you not familiar with a skeleton blurb, it is a simple sentence that captures the heart of your story. Using only the protagonist, the story goal, and the story stakes, you can create a sentence that you can use as a touchstone for every scene in your story. I’ll write more about this in the near future.

I’m sure you already have ideas for your protagonist.

The Secret to Bestselling Fantasy:The Magic of Opening Images and First Chapters

The first page of a fantasy novel isn’t just paper and ink—it’s a portal. But how do you ensure your readers actually want to step through it? In our latest guide, Secrets to Writing a Fantasy, we pull back the curtain on the mechanics of world-building, starting with the two most vital components of your debut: the Opening Image and the Opening Chapter.

While they sound similar, understanding the nuance between them is the difference between a reader who browses and a reader who buys.

The Opening Image: Setting the Tone

The opening image is the very first visual or conceptual seed you plant. In fantasy, this often takes the form of “pre-text”—perhaps a haunting quote from a fictional ancient tomb or a snippet of a forgotten prophecy.

Its primary duty is to support two pillars: the external plot and the supernatural plot. You may want to check out Why Your Story Needs Two Story Arcs. You have a crucial choice here: does your “ordinary world” include magic from the start, or is the supernatural something that breaks into a mundane reality? Your opening image sets that expectation immediately. Here are some options for what this scene can accomplish.

  • Establish life-or-death stakes.
  • Hint at what the protagonist loves (and what they stand to lose).
  • Set the atmospheric tone before a single line of dialogue is spoken.

The First Chapter: The Engine of Engagement

If the opening image is the atmosphere, the first chapter is the engine. This is where genre-agnostic duties kick in. Regardless of whether you have dragons or starships, your first chapter can:

  1. Introduce the Protagonist: Unless there is a high-level narrative reason to wait, the reader needs someone to root for now.
  2. Define the Ordinary World: This is the status quo. We need to see your hero in their natural habitat before the inciting incident blows it all to pieces.
  3. Mirror the Closing Image: Expertly crafted novels often begin with a visual or thematic beat that finds its “answer” or reflection in the final pages of the book.

Case Study: Fourth Wing by Rebecca Yarros

In Secrets to Writing a Fantasy, we analyze bestsellers to see these rules in action. Take Fourth Wing.

Yarros utilizes a powerful opening image: a paragraph explaining that the text was transcribed by a scribe to honor the dead. This immediately signals that the stakes are lethal. She follows this with a quote from the Dragon Rider’s Codex, weaving the supernatural (dragons) into the very fabric of the world before Chapter One even begins.

When we reach Chapter One, we meet Violet Sorrengail. Her ordinary world is a library, but the inciting incident—her mother forcing her into the Riders Quadrant—has already happened. Yarros uses clever backstory beats to show us what Violet is leaving behind, proving that you don’t need a linear timeline to create an emotional connection.


Excel at the Art of the Beginning

Are you showing the ordinary world in action, or are you weaving it through backstory? Is your tone consistent from the first sentence?

Don’t leave your opening to chance. Whether you’re writing a grimdark epic or a cozy portal fantasy, the transition from the “Opening Image” to the “Opening Chapter” is your first and best chance to cast a spell on your audience.

Don’t leave your structure to chance. Stop guessing and start building a structurally sound novel, scene by sensational scene.

From Shake-Up to Finale: The 5 Essential Scenes Every Story Needs

I’m thrilled to be a guest on the Rakuten Kobo Inc. Writing Life blog to share the 5 Essential Scenes Every Story Needs.

Every novelist wants to write a book that keeps readers turning pages until 2 AM. But without these five structural pillars—the Inciting Incident, Plot Point 1, the Midpoint, Plot Point 2, and the Climax—even the best prose can lose its momentum.

In this post, I break down why these scenes are the “make or break” moments for your narrative arc.

Romance: Keeping the Promise

One of the most common questions I hear when I tell people I co-authored a craft book on writing romance is, “Does it really have to end with a happily ever after?” The short answer is yes. The longer answer is far more interesting, because it gets to the heart of what makes romance such a powerful and enduring genre. If you’re new to writing romance, understanding this expectation will save you a lot of confusion and revision down the road.

Romance isn’t defined by the presence of a love story. Plenty of novels contain love stories — literary fiction, thrillers, historical, even horror. A romance is defined by its promise: the central relationship must resolve in a way that is emotionally satisfying for the reader. In other words, it must end with either an HEA (Happily Ever After) or an HFN (Happy For Now). Think of an HEA as “we’re in it for the long haul” and an HFN as “we’re together and happy, and we’ll see where life takes us.”

This isn’t a formula. It’s a contract.

When a reader picks up a romance, they’re entering into an agreement with the author. They’ll endure the wounds and fears, the complications and obstacles you put in the character’s path, trusting that, in the end, their heart is safe. The HEA/HFN is the fulfillment of that promise. It’s the moment when the emotional arc lands, the internal epiphanies click into place, and the characters choose each other in a way that feels earned.

An HEA is the classic version: the couple is together, committed, and looking toward a shared future. It doesn’t require a wedding, a ring, or a baby. It simply requires clarity: the reader closes the book knowing the relationship is solid, and the characters have done the work to make it last.

An HFN offers a future that’s hopeful, even if it’s not fully mapped out. HFNs are especially common in romance series arcs or in stories where the characters are still in transitional phases of life. The key is that the ending feels emotionally complete, even if the future isn’t yet spelled out.

If you’re new to romance, you might worry that this makes your story predictable or less “serious.” In reality, readers choose romance because they want that emotional payoff. Your job isn’t to surprise them with whether it ends happily, but to surprise and move them with how it happens. Genre expectations don’t limit creativity; they shape it. Mysteries must solve the crime. Thrillers must stop the threat. Romance must resolve the relationship. Readers want to feel hopeful and secure about the couple’s future. Within that framework, authors set their stories apart through character depth, emotional complexity, unique conflicts, and fresh settings. The HEA/HFN simply ensures that the emotional journey lands where romance readers need it to.

And readers do need it. Romance is one of the few genres that consistently affirms hope — not in a naïve way, but in a deeply human one. These stories remind us that people can grow, relationships can heal, and love is worth the risk. In a world that often feels chaotic and uncertain, that promise matters.

So yes, a romance requires an HEA or HFN. Not because the genre is rigid, but because the emotional payoff is the point. It’s what makes romance comforting, cathartic, and profoundly satisfying. It’s what keeps readers coming back. And it’s what makes writing romance such a joyful, meaningful pursuit.

Secrets to Writing a Mystery

Mysteries offer readers a unique experience. As well as being drawn into the life of a character, the reader also enjoys the challenge of solving the crime along with the sleuth. The reader uncovers clues and examines all the evidence to deduce motive and opportunity for every suspect with the goal of finding the culprit among them.

Whether they lean into the emotional community connection found in many cozies or the sometimes gritty mental distance and challenge in police procedurals, all mystery readers appreciate the twists and turns offered by a mystery writer.

Mystery writers weave this web, building from the solid foundation of mystery structure that supports the strands of surprise. Writing a mystery offers a challenge by integrating the unique and surprising into a familiar and expected structure. For mystery readers, the knowledge that the sleuth will uncover the culprit doesn’t diminish the thrill of the chase.

Instead, it allows them to trust that the writer will include every clue needed to discover the truth. The climax can come as a surprise or a confirmation for the reader, but it always delivers a sense of satisfaction. The story world may be different than it was at the start of the novel, but there is a sense that at least there is justice in the world.

Writing a great mystery requires both meeting the reader’s expectations for specific genre elements and adding your story’s unique twists.

The desire to help writers understand the underlying secrets to writing a compelling mystery that meets readers’ expectations and opens ideas for creativity in storytelling inspired Kristina Stanley and me to write Secrets to Writing a Mystery.

Deep analysis of the structure found in commercially successful mysteries uncovered clues. By identifying what the mysteries have in common as well as their unique twists, we discovered a framework that we hope will inspire every writer to find the path for their mystery. In our book, we share insights and tips aimed to support writers’ creativity while equipping them with the necessary tools to craft their best mystery.

One of the first secrets we unlocked is that a mystery novel solves a crime by answering who committed that crime and why. There are different types of mysteries. We focused on three subgenres that encompass many mysteries: amateur cozy, amateur traditional, and detective. These types share several common aspects:

  • The reader learns about the crime early, often on the book jacket description or from early events in the story.
  • Neither the reader nor the protagonist knows who the culprit is at the beginning of the story.
  • The protagonist might not be in danger at the beginning of the story.
  • The protagonist solves the crime in the climax scene.
  • There will be multiple suspects until the climax scene.
  • In most novels, the antagonist isn’t known until the climax scene.

Do you have an idea for the crime in your book? Write it down. If not, don’t worry. The crime will become clearer as you make other decisions about your story.

I will be sharing insights and unlocking more secrets from our book to inspire your writing. From victims to suspects and clues, through structure and genre expectations, watch for new insights each week.

And if you can’t wait, Secrets to Writing a Mystery is already available to help you solve your own mystery and write your book.

We really hope you do, we love reading mysteries!

The Secret to Bestselling Fantasy: Why Your Story Needs Two Arcs

The Power of Two Arcs

Did you know that every commercially successful fantasy novel actually contains two complete story arcs?. Discover how to weave a high-stakes external adventure together with a gripping supernatural journey to create a narrative that satisfies every reader’s expectation.

Most fantasy writers start with a spark of magic—a unique dragon bond, a complex spell system, or a world-ending curse. But somewhere between that initial idea and the finish line, many manuscripts stall because they lack the foundation to support such a complex narrative. If you’ve ever felt like your plot is a “jumbled ball of words,” the solution isn’t adding more magic; it’s writing using deep structure.  

Before you get down to the level of copy editing or proofreading, make sure your story structure is strong. You can do this while you write your novel, or you can do this during the self-editing phase.

In Secrets to Writing a Fantasy, we reveal one of the most powerful patterns found in commercially successful novels: the dual-arc system.  

The Two Hearts of Your Story

A sensational fantasy novel is a perfect balance of two distinct but intertwined plot lines :  

  • The External Plot: This is the universal adventure narrative. It is the challenge issued to your protagonist that forces them to leave their ordinary world. Without this, you don’t have a story.  
  • The Supernatural Plot: This is the unique factor that satisfies genre expectations. It tracks the protagonist’s journey from their first inkling of magic to harnessing (or losing) it in the final battle. Without this, you don’t have a fantasy.  

Weaving The Story Arc Scenes

The key to a page-turner is how you weave these two arcs together. Every story needs five core “story arc scenes” to form its spine: the Inciting Incident, Plot Point 1, Middle Plot Point, Plot Point 2, and the Climax.  

In a fantasy novel, that means you are actually managing ten pivotal moments—five for the adventure and five for the magic. When you align these scenes, you create a story that is both balanced and believable. For example, the supernatural inciting incident often happens right after the external one, proving to the reader that your character isn’t just on an adventure—they are on a magical one.  

The Guiding Light: The Combined Skeleton Blurb

How do you keep track of all these moving parts without getting lost? It starts with a Combined Skeleton Blurb. This single sentence captures your protagonist, their dual goals, and the high-stakes consequences of failure.  

Formula: [The protagonist] must [external goal] and [supernatural goal]; otherwise, [external stakes] and [supernatural stakes].  

By defining this promise early, you ensure that every scene you write—from the first goal attempt to the final resolution—works hard to support your story’s core mission.  

Don’t leave your structure to chance. Stop guessing and start building a structurally sound novel, scene by sensational scene.  Read Secrets to Writing a Fantasy and write your best novel.
