Thriller

Thrillers are designed around momentum. Information arrives at exactly the wrong moment, motives keep changing, and each chapter closes with a reason to read the next one. The social-media favorites here range from domestic suspense and locked-room mysteries to supernatural danger and literary thrillers.

Where to start: Psychological thrillers keep the danger close to one unreliable point of view. Domestic suspense turns homes and relationships into traps, while mystery-thriller hybrids put more weight on solving the crime. Check the horror shelf when you want the threat to feel less explainable.
