Nobody does scarily plausible near-future like Marrs. This - his best yet - is an unsettling and immersive roller coaster which hurtles towards a chilling denouement - a truly thought-provoking, single-sitting thriller. Loved it. -- Ellery Lloyd, bestselling author-duo of The Club and People Like Her

John Marrs is a writer at the top of his game and The Family Experiment is his best yet. Frighteningly plausible, gripping, dark, and so clever, I raced through this original, high-concept thriller unable to put it down. A thought-provoking examination of what family means. Superb. -- Claire Douglas, bestselling author of The Woman who Lied

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

The Family Experiment is an eerie and darkly addictive thriller that will have your mind whirling throughout. - Culturefly

Clever, compelling and terrifyingly plausible. A near future nightmare that grips from the first page and never let’s go. The Marriage Act is a brilliant examination of relationships and the power we let others have over us. And talk about a page-turner. This one will leave you with paper cuts! -- C. J. Tudor, author of A Sliver of Darkness on The Marriage Act

John’s creative, high-concept thrillers never fail to keep me furiously turning the pages and The Marriage Act is no exception. Pacy and packed full of tension, the book kept me constantly guessing as the thought-provoking plot about marriage and everything that comes with it unfolded in the most sinister of ways . . . dark, immersive speculative fiction at it’s very best! -- Sarah Pearse, author of The Retreat and The Sanatorium on The Marriage Act
