John Marrs is an internationally bestselling author of psychological thrillers and speculative fiction. Before becoming a full‑time writer, he spent more than two decades as a freelance journalist interviewing celebrities for national publications.

He self‑published his early novels while commuting to work, building a passionate readership through social media that helped attract Amazon Publishing and Penguin Random House.

His breakout book, The One, became a No. 1 Netflix series, has sold over a million copies, and is published in 35 languages. His other bestselling titles include The Good Samaritan, What Lies Between Us, The Passengers, The Marriage Act, and The Stranger in Her House.

John continues to explore the darker sides of human nature across both genres. His next thriller, Dead In The Water, publishes in January 2026.
