Suspense thrillers are notable for the building of tension and unease. From the first pages there is danger lurking, and the story line unfolds with characteristically fast pacing. Many books feature the thoughts of both the hero and the villain, which only heightens the sense of "suspense" and constant tension.
Famous suspense writers are John Sanford, James Patterson and C.J. Box. For a blend of suspense and romance, see romantic suspense.
