Should You Turn Your Idea into a Novel?

Story Premise

You’ve scanned the internet for help to make your decision, but seriously, how do you choose whether to turn your idea into a novel?

It’s not magic. You don’t need a committee to hash out the details. Instead, ‘Validate Premise’ is the second step in the Trellis Method, and one you don’t want to skip.

When you validate your premise, it turns an idea into your strategic guide, one that will lead you from the start to the finish of writing a full-length novel.

Decide Whether to Turn Your Idea into a Novel

As with most things in life, a process replaces worry with an action plan.

When you validate a premise, you’re following in the footsteps of some great writing teachers, such as scriptwriter Blake Snyder. For instance, in his classic book Save The Cat!*, Snyder wrote:

Validate Premise then Turn an Idea into a Novel

Another excellent writing teacher, John Truby, gave us the premise validation process, and in his book The Anatomy of Story*, Truby wrote:

Then Truby provided these useful examples:

What’s wonderful about these examples is we can view the films and discern their premises in a few hours instead of spending days or weeks reading the novels.

The Importance of a Validated Premise

In The Anatomy of Story, Truby made this bold statement.

My mind translates Truby’s statement into this…

After all, unqualified ideas are a dime-a-dozen, but a validated premise serves as your writing strategy, and that’s priceless!

Create Your Story’s Premise

Truby coaches how to turn an idea into a premise using these steps:

  • Write something that may change your life and look for what’s possible.
  • Identify the story challenges and problems.
  • Find the designing principle. (Your overall story strategy, stated in one line, is what organizes the narrative and makes it original.)
  • Determine your best character in the idea.
  • Gain a sense of the central conflict.
  • Identify the single cause-and-effect pathway.
  • Determine your hero’s character change.
  • Figure out the hero’s possible moral choice.
  • Gauge the audience appeal.

Based on Truby’s advice, here’s my infographic of the recommended actions:

Turn Your Idea into a Novel Readers Will Love

An overwhelming number of top writers master their chosen genres.

That means they’ve read, adopted, and adapted the time-tested masterworks to come up with fresh approaches to telling great stories. The best storytellers win the war of commercial fiction, and you can adopt their practices too. For example:

  • Understand how and why your competitors tell their stories the way they do.
  • Choose to write, but tweak your story in fresh ways.
  • Take to heart target audience comments and tell stores that not only satisfy their expectations, but surprise and delight readers.

How to Gauge Your Book’s Audience Appeal

A big mistake writers often make is thinking their idea will automatically have audience appeal.

Fortunately, we have an enormous database on Amazon brimming with examples of what readers not only want to read but will purchase. Follow these steps to validate your carefully constructed premise to determine if readers buy books like your premise.

  1. Visit Amazon and type into the search box key phrases from your premise.
  2. Analyze the sales page for each book by viewing the ‘ranking’ shown down in the Product details section (e.g., The Da Vinci Code ranks #86 in Historical Mysteries as of August 22, 2024).
  3. Outflank your competitors by identifying in the reviews what readers like and dislike, and then write to exceed those audience expectations.

You can keep track of your discoveries in a text file or organize the findings in a spreadsheet, but most importantly, do this:

Validate Your Premise Using Three Criteria

If you want to save hours, improve research results, and increase your confidence, consider the three validation criteria offered by the creator of Publisher Rocket*, Dave Chesson.

Try a Manual Search to Validate Your Story Idea

Type your story idea into the Amazon search field and you’ll see the platform auto-complete the phrase with what shoppers entered.

For example, let’s say your idea is a cozy mystery where the murder takes place at a local sushi bar.

  • As you type ‘murder at’ into the search box, Amazon starts auto-completing your phrase with several possibilities.
    • Data: … the pumpkin pageant, … the white palace, … Karlov manor mtg, … the book club, … The Vicarage by Agatha Christie, … The Breakers, … Vinland by Alyssa Maxwell, … The White Palace by Allison Montclair, … Spindle Manor, … Vinland
    • Conclusion: You do not have an actionable sense of how many people actually searched for these phrases.
  • You can force Amazon’s search box to give you another range of answers by entering an additional letter (e.g., ‘murder at a’), and you’ll often see several additional possibilities.
    • Data: … a cape book store, … an Irish wedding, … an Irish Christmas, … an Irish bakery, … an Irish baker by Carlene O’Connor, … an Irish chipper, … an English pub, … Ashton steeple Heathcliff Lennox, … a Scottish castle, … Archly manor
    • Conclusion: You may see nothing that helps you decide if your story idea is valid.
  • If you type ‘murder at a sushi bar’ into the search box, you would expect to see more auto-complete possibilities.
    • Data: Amazon’s search engine listed nothing else.
    • Conclusion: If you hit enter, the results page shows a list of books that have nothing to do with either sushi or sushi bar.

You could type ‘murder at’ followed by one letter of the alphabet and discover many possibilities, including books that might parallel or compete with your story idea.

Still, it’s unlikely your research will produce enough quality information for decision making, and that’s frustrating to spend all that time if you can’t:

  • Discover a pre-existing market.
  • Find out whether people will pay for your story idea.
  • Determine if the competition will allow your book to compete successfully.

Fortunately, there’s an app that helps you:

  • Identify the actual keywords people type into Amazon to search for books.
  • Decide whether your story idea is viable commercially.
  • Determine if the competition allows enough room for your book to succeed.

Use Publisher Rocket to Validate Your Story Idea

The Publisher Rocket app captures the key phrases people type into Amazon’s search engine and converts those details into information you can use to validate your premise.

For example:

  • Publisher Rocket lists all of Amazon’s auto-complete suggestions.
  • The software tells you how many people typed keyword phrase into Amazon each month.
  • The app makes it easy for you to interpret the results by color coding the keywords that are more likely to work.

Here’s an example of Publisher Rocket’s results when you type ‘murder at’ into Amazon’s search box:

Searches that Shout ‘NO GO!’ for a Story Idea

If we enter ‘murder at a sushi bar’ into Publisher Rocket, we get this result:

This result shouts ‘NO GO! and we need to search for an idea with more potential.

Search for Profitability and Competition

Publisher Rocket enables you to test whether a story idea has potential profitability and reasonable competition.

Step 1. As an example, let’s type the keyword phrase ‘murder mystery’ into Publisher Rocket’s Keyword Search field.

Step 2. We review the results, and keep searching for a satisfactory combination of the ‘Average Monthly Earnings,’ the ‘Number of Competitors,’ and the ‘Competitive Score.’

Note: Ideally, you want to find keyword phrases for a story idea that has a reasonable ‘Number of competitors’ (i.e., a pre-existing market), a high number of ‘Estimated Amazon Searches/Month’ (i.e., people hunt using a specific keyword phrase), a low ‘Competitive Score’ (i.e., you have a favorable chance to enter this market).

Step 3: Repeat steps 1 and 2 until you find the right combination of story idea that allows you the greatest potential to discover a pre-existing market, prove people will pay for your story idea, and the competition is low enough for your book to compete.

Research the Potential of Story Ideas You Like

I love a good murder mystery, so let’s see what Publisher Rocket shows for the keyword phrase ‘murder mystery’ as we scan down the multiple pages.

Two of the listings show green codes for the Estimated Monthly Earnings and Competitive Score.

  1. The keyword phrase ‘murder mystery cruise ship’ gives us green highlights for the ‘Estimated Amazon Searches/Month’ and the ‘Competitive Score.’ However, the ‘Average Monthly Earnings’ are only $237.
  2. The keyword phrase ‘murder mystery for teens’ has green highlights for the ‘Estimated Amazon Searches/Month’ and ‘Competitive Score,’ plus the ‘Average Monthly Earnings’ increases to $3,282.

The excellent potential for the second keyword phrase deserves more research.

Are there exceptions to this writing principle?

It’s a principle, not a rule, so there’s bound to be exceptions, but if your goal is to write a book readers will love, do the research first.

  • Find a pre-existing market.
  • Choose a keyword phrase used by people who buy books.
  • Make sure the market has room for your book to get noticed.

And if you want to simplify the process, blast off with Publisher Rocket*.

    Wow, Grant, what a wealth of information. I never do any of the market testing, and probably should, though I’m not sure it would change my direction once a story has settled into the old brain matter. Lots to consider here. Thank you!

      You’re welcome, Diana. There’s never a single path, and we should all do what’s best for our goals. I appreciate you contributing to the discussion!

        If I was younger…. And planned to make a living as an author, I would probably approach book-planning and market vetting differently. It becoming more and more something I do for fun.

    A fabulous post, as always! The amount of depth and information you provide is so appreciated. I’m definitely taking notes! Even though I’ve managed to find some novel-worthy ideas, there are still those which I’m a little on the fence about. So thank you for the much-needed advice!

    1. Grant at Tame Your Book Avatar

      You’re welcome, Damyanti. I love sharing the best of what the top writers already figured out. By marking the trail, my goal is to show others they can write a book readers will love.

    Like you suggest, I write down a bunch of story ideas (without judgement) then go back and tweak the ones that interest me until I find one with depth and uniqueness.

    1. Grant at Tame Your Book Avatar

      That’s a great process, Priscilla. It makes a difference, increasing the potential the story will resonate with readers. I appreciate you dropping by today!

    Great suggestions. It took me over 25 years to get my first prehistoric fiction out, mostly because I was struggling with this very question. Where were you 25 years ago?

      As Scotty of Star Trek might say, “Aye, Captain, sorry it took so long, and I found out why. The emergency bypass control of the matter/antimatter integrator was fused — completely useless — so it took time.” Kidding aside, I always appreciate your insights, Jacqui!
