Replaceable You

‘This book is so good… Replaceable You by Mary Roach is all about how in the future, we will be able to replace every organ in our body that fails.’ —Reese Witherspoon

‘Mary Roach offers a fascinating tour of the wonderful world of regenerative medicine.’ —TIME, The Most Anticipated Books of Fall 2025

‘Mary Roach has had a more direct impact on my career than any other writer. She is her own genre of book – gonzo, hilarious, wildly educational. This is Roach at her finest.’ —Daniel Kraus, author of Whale Fall

‘Full of engaging accounts of scientific advances in the field of the human body. It’s a frightening portrait of the gruesome experiments people are prepared to undergo in the pursuit of becoming more attractive… Roach is an intrepid reporter and adept at explaining complicated procedures clearly.’ —The Times

‘Mary Roach leaves no stone unturned in her quest to explore the limits of regenerative medicine. The seasoned science writer has mastered the art of explaining complex topics in a way that is digestible for the reader, with a healthy dose of characteristic humour… This is a book that makes you feel clever while also making you laugh.’ —Daily Mirror

‘We are all replaceable to some degree or another… with the exception of Mary Roach. There is no one and nothing like her – singular, bizarre, dedicated, passionate, fascinating. Her writing traffics at the unusual intersection of science, storytelling and humor. That is a very tricky intersection to navigate, and no one does it as masterfully or consistently as she. I devour everything she writes.’ —Jason Alexander

‘In her brilliant (and brilliantly funny book) Replaceable You, Mary Roach explores the puzzle of the human body, the way we can assemble and reassemble the very human pieces into different versions of who we are and how we work. The result is intriguing, compassionate, wise and – as with all her books – addictively readable. Or to put this another way: Don’t miss it.’ —Deborah Blum, bestselling author of The Poisoner’s Handbook
