Writing thriller books
Something terrible is coming. Can they stop it in time?
Where a mystery looks back at a crime, a thriller looks forward at a threat. The reader often knows more than the hero, and the tension comes from watching danger close in. Short chapters, high stakes and a ticking clock are the tools of the trade.
What readers expect
- A clear, escalating threat
- A hero under pressure
- Twists and reversals
- Pace: little time to breathe
A tip before you start
Put a clock on it. A deadline the reader can count down turns every scene into a race.
