John Marrs is a British author of psychological thrillers and speculative near-future fiction, best known for turning irresistible “what if” ideas into fast-moving suspense. Before writing fiction full-time, he worked as a journalist, a background that shows in his sharp... hooks, multiple viewpoints, and short chapters built around escalation. His breakout novel The One, later adapted by Netflix, helped define his Dark Future stories, where technologies such as DNA matching, autonomous vehicles, data storage, and state-controlled marriage expose human fear, ambition, and moral weakness. Alongside those speculative thrillers, novels such as What Lies Between Us and Keep It in the Family show his darker domestic-suspense side. Marrs appeals to readers who like accessible high-concept premises, twisty reveals, and unsettling questions about how well people know the systems they trust.
