"Replaceable You by turns surprises and delights, revealing information that even I didnt knowThese curious facts, with attendant and laugh-inducing footnotes, keep us turning the pages, but the real power of the book lies in its humanity." -- Brandy Schillace - Wall Street Journal "Readers will feel awe at all the body can do and how it is made, as well as admiration for humanitys persistence in exploring its limitswhether when confronted with a malfunctioning organ or the desire for a more plump derriere. Replaceable You will delight Roachs fans and surely garner some more." -- Kelly Blewett - Bookpage "Since she burst onto the scene with 2003s Stiff: The Curious Lives of Human Cadavers, the science writer Mary Roach has been grossing readers out with curiosity, humanity and alarming gusto. And we cant look away." -- Sadie Stein - The New York Times "Mary Roach offers a fascinating tour of the wonderful world of regenerative medicine." -- Time "The humanity that [ Roach] brings is such a wonderful base for how our bodies fail us sometimes and what we are trying to do to bring them back." -- LA Times, The 5 Best Science Books of 2025 "A veteran science writer returns with a whirlwind tour of body modification and repair . . . what Roach does best sounds simple but isnt: She meets people and gets them to talk about complex subjects in a way that is approachable, understandable, and graspable." -- Christopher Kemp - Science Magazine "The subject matter can be grimly fascinating and isnt for the squeamish, but Roach tackles it with the same energy and sense of humor she brought to previous books on cadavers, space travel and sex. She follows her curiosity wherever it leads whether thats a pig farm in the Chinese province of Sichuan; a Tblisi, Georgia-based surgery practice that specializes in penis transplants; or the inside of a 1950s-style iron lung." -- Alice Robb - Bloomberg "In her latest book, author Mary Roach does what she does best: she selects a squirm-worthy subject (past examples have included cadavers, digestion and
copulation) and transforms it into a lively tale of science and the human endeavor. . . . Some organs may be replaceable, but the endlessly endearing and fascinating Mary Roach is not." -- Brianne Kane - Scientific American "This book is so good and it's on my list because it's right on topic with Gone Before Goodbye. 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 "We are all replaceable to some degree or another . . . with the exception of Mary Roach. There is no one and nothing like hersingular, 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, actor/director "Mary Roach has had a more direct impact on my career than any other writer. She is her own genre of bookgonzo, hilarious, wildly educational. This is Roach at her finest." -- Daniel Kraus, author of Whale Fall "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 andas with all her booksaddictively readable. Or to put this another way: Don't miss it." -- Deborah Blum, best-selling author of The Poisoners Handbook "[ Roach] uses her access, opportunity, and general lack of squeamishness or shame to ask questions with her characteristic empathy and clarity and shares her experiences in witty and engaging prose laden with amusing footnotes. A treat for Roach admirers, this book also serves as an excellent introduction to her body of work. . . . This approachable and humorous explainer will delight the scientifically curious." -- Wade Lee-Smith - Library Journal (starred review) "Science writer Roach engagingly explores the past, present, and future of fabricated replacement body parts and regenerative medicine. She has previously penned books about the body, including Gulp (2013), and brings her distinctive nonfiction writing style, headlined by curiosity, enthusiasm, and lots of humor, to this subject, too. . . . Highly recommended reading for those curious about 'fixes' for the body and the world of biotechnology." -- Tony Miksanek - Booklist (starred review) "An amiably entertaining, endlessly intriguing stroll through the stuff of which were made." -- Kirkus (starred review)
