What Defines the Thriller Genre

Thriller: The Threat, the Tension, and the Twist

A thriller is an engine built to keep the reader’s pulse up. It runs on four things working together — a high-stakes threat, relentless escalating tension, a protagonist the reader is desperate to see survive, and the twists that keep the outcome in doubt right up to the end.
