Sounds great!

You'll need a protagonist whose personal goal is to find that answer, and for whom the stakes are high and get higher. It's best if your protagonist is interesting, likable, and/or sympathetic to your readers. Finally, a succession of plausible obstacles or opponents.

One storytelling guide I've found useful: protagonist faces at least six good/good or bad/bad dilemmas throughout the story.

Best of luck! Persist!
