Praise for The Family Experiment
"The books of John Marrs have become a quiet phenomenon . . . Thoughtful, well written . . . and alarming."—Daily Mail
"The Family Experiment is an eerie and darkly addictive thriller that will have your mind whirling throughout."—Culturefly
"His best yet. Frighteningly plausible, gripping, dark, and so clever."—Claire Douglas, author of The Woman Who Lied
"An unsettling and immersive roller coaster which hurtles towards a chilling denouement—a truly thought-provoking, single-sitting thriller. Loved it."—Ellery Lloyd, author of The Club
"Chilling, inventive, horribly plausible and brilliantly addictive."—C. J. Tudor, author of The Gathering
"It's so, so, good. This book deserves to be huge. It’s speculative fiction at its very best—original, dark and wickedly clever. I was utterly captivated by the way Marrs melded reality TV, AI and a terrifyingly plausible future. He's created a terrifyingly plausible world. The world building, the characters, the reveals and the twists are so well done that this book is crying out for a Netflix adaptation."—C. L. Taylor, author of Every Move You Make
