How to use this list
These are starting points, not finished stories. Take one, change the setting, swap who it happens to, collide two of them. Most good novels come from an idea that got twisted until it belonged to the writer.
Each card gives you:
- Genre: where it would sit on a shelf
- Shape: a structure that suits it
- Scope: standalone, or with room for a series
- The hard part: what will decide whether the book works
When one sticks, capture it before it wanders off. Our idea journal guide explains why that matters more than you'd think.

How to tell if a novel idea will last
Lots of ideas are exciting for a weekend. Novel ideas have to hold up for a year or more. Before you commit, try these tests:
- The one-sentence test. Can you say who it's about, what they want, and what's in the way, in one sentence? If not, the idea may be a setting or a mood, not a story yet.
- The middle test. Can you imagine at least five things that happen in the middle of the book? Many ideas are a great opening and a great ending with nothing between.
- The obsession test. Did you think about it again the next day without trying? Ideas that keep coming back on their own have the most fuel.
- The "why you" test. What do you know, love, or fear that makes this your book and nobody else's?
- The "what if" test. Push the premise one step further. If it gets more interesting, it has room to grow.
From novel idea to first draft
- Capture it fast, with the date, before it fades. A sentence is enough.
- Write the premise: a paragraph with your character, their want, the obstacle, and the stakes.
- Find the ending, even roughly. You can change it later, but a destination makes the middle easier.
- Sketch the big turns: the opening, the moment everything changes, the midpoint, the lowest point, the climax.
- Write the first chapter to find the voice, then decide whether to outline more or keep discovering.
- Give it a home. Keep the draft, notes, and versions together. A Writing Room keeps every version of your draft as you go, and lets you write with a partner or share it with a writers' group.
Frequently asked questions
What are some good novel ideas?
Good novel ideas pair a specific character with a situation that forces them to change. For example, a debt collector who discovers her city's magic was never paid for, or a nurse who learns the residents of a care home never speak between 3 and 4 a.m. The list above has 60 more, sorted by genre.
How do I come up with an idea for a novel?
Start with what you already care about: a place you know, a question you can't answer, a fear, a job you've had. Then ask "what if?" and push it further. Keeping an idea journal helps too, because the best novel ideas often come from two smaller ideas meeting months apart.
What is a premise in a novel?
A premise is a short summary of the story's core situation: who it's about, what they want, and what stands in their way. It's usually one to three sentences, and it's the best test of whether an idea can carry a whole book.
How long is a novel?
Word counts vary by genre and audience. Adult novels are commonly cited at around 70,000 to 100,000 words, with some genres, like epic fantasy, running longer, and young adult novels often running shorter. Check what's typical for books like yours.
What are the 7 main types of stories?
One popular framework, from Christopher Booker's book The Seven Basic Plots, lists overcoming the monster, rags to riches, the quest, voyage and return, comedy, tragedy, and rebirth. It's one way to think about story shapes, not a rule.
Can I use these ideas for my own novel?
Yes. Take them, twist them, make them yours. An idea isn't a book. What you do with it is.
