The ending and the Storycoaster
The ending and the Storycoaster
The Storycoaster structure doesn’t just apply to individual scenes. The Storycoaster serves as the blueprint for your entire story-length arc. While every scene needs its own rhythmic buildup and release, your ending is the ultimate destination that fulfills the promises of your story’s long-term tension about whether or not your main character achieves their goal. To craft a truly engaging conclusion, you must transition your reader from the highest point of tension down to a satisfying resolution, which often involves these three final stages:
1. The highest peak - the final “It Happens”
This is your story’s climax. This is the "final boss fight" where the protagonist must take the most decisive action to either achieve their story-level goal or let it go. It is the moment of maximum tension where they lay everything on the line and exert the most physical and/or emotional energy.
In a romance, this is the point where the protagonists must finally confront how much they have to change or what fears they must overcome to truly be together.
If you are stuck trying to come up with an ending, think of your character’s greatest fear or the one thing they said they would never do, and make them do it here.
2. The final plunge - the immediate consequences
Once the "It Happens" moment of your story’s highest Peak is triggered, your narrative enters the Plunge. This is the immediate, high-emotional aftermath where the consequences of your protagonist's most decisive actions ripple through their world and their being.
This doesn’t have to be a huge part of your ending, but it’s important for your readers. All the tension and emotional promises you built during the story's long "Climb" must finally pay off for the reader. They want to experience the raw emotional impact as the character either finally achieves their goal or is forced to let it go forever.
3. The final valley - the new baseline
Following the final Plunge, the story de-escalates toward its conclusion, establishing the Ending State, the last image the reader will have of the main character. This is the final Valley where your protagonist settles into a new baseline.
The Valley answers the question, "What changed?" Use this section to show the lasting impact of the character's journey. If the main character achieved their goal, what does their new life look like? If they failed or had a change of heart, how have they adjusted their world to fit this new reality? Compare your character's final emotional state to their "Beginning State".
In a fantasy or sci-fi story, the core character arc often involves moving from a Beginning State of powerlessness or ignorance to one of mastery and responsibility. This final Valley should demonstrate that the protagonist is in a more significant position than they were in Chapter 1. For example, a farm boy who began the story fearing the local lord might end it as a seasoned commander who understands the weight of leadership. Or, a cynical space scavenger who starts the story only caring about their next paycheck might end the story as the navigator of a multi-species resistance movement. Or, a brooding mafia hitman who begins the story isolated and bound only by a violent code of duty might end it having unthawed his cold exterior to embrace a life of vulnerability and commitment with his partner. While they have reached a state of de-escalation, this Ending State is a much "higher Valley" because the baseline of their capability and the stakes they manage have been permanently raised.
Ending your story with a cliffhanger
While every chapter in your book can (and ideally should!) end with a cliffhanger of some kind, ending an entire book on a cliffhanger can be a delicate balancing act. To keep a reader engaged for a sequel, or just to end your standalone story on a thrilling high, you must provide enough resolution to reward your readers while denying enough resolution to get them thinking, “I wish I could find out what happens next right now!”
Here are a few tips and tricks for ending your story with a cliffhanger:
Resolve the immediate conflict: Readers need a major resolution to feel their investment in your story was warranted. By the end of the book, the main character must either succeed or fail at the specific goal they've been striving for. For example, if the entire book was about finding a lost magical artifact, the ending must confirm whether they found it or not. If the goal was for the couple to finally admit their feelings, they must do so. After this resolution, you can pose a new question or throw a new challenge at your characters before ending the story.
The Plunge cut: Use the Storycoaster to find the perfect cut-off point. Instead of letting the story settle into a long, quiet Valley (the "Ending State"), cut the narrative during the Plunge—the slope of consequences immediately following the Highest Peak. This allows the "It Happens" moment to land, but leaves the long-term fallout as an open question for the next installment.
Use emotional cliffhangers: A book-level cliffhanger doesn't always have to be a life-or-death plot event. Some of the most effective endings come from a character’s internal change. A sudden crisis of conscience, a change of heart, or a shocking revelation about a loved one can be just as compelling as a physical threat.
Avoid the "unrelated" cliffhanger: Avoid ending with an external factor that doesn't flow from the story you've established, like the leads being about to kiss and one of them suddenly being hit by a car. This redirects the reader's focus and feels like a cheat rather than a narrative payoff.
