Standalone Thrillers Books in Order

The standalone thrillers of Kate Alice Marshall are atmospheric, often horror-adjacent suspense novels that draw on genre conventions — urban legends, haunted locations, isolated communities — to construct mysteries with genuine psychological tension. Marshall writes in a mode that sits at the intersection of YA thriller, horror, and adult psychological suspense, with a gift for settings that feel threatening and characters whose past mistakes create present danger.

Rules for Vanishing (2019) is her most celebrated novel — a found-footage style YA horror thriller structured as testimony and documents about a group of teenagers who walked a road that leads to a girl who vanished and never came back. No One Can Know (2024) represents her move into more explicitly adult suspense.

Marshall's work has found audiences across the YA and adult thriller markets, with her atmospheric writing and genre-blending sensibility appealing to readers who want their suspense to carry genuine uncanny weight. Individual novels stand completely alone.
