Mary Roach is a bestselling science writer and explorer of the the odd corners of science that most people wouldn’t dare to investigate. Cadavers, sex labs, space junk, you name it.

Her new book, Replaceable You, takes that curiosity inside the body itself, exploring the world of prosthetics, organ printing, regenerative medicine, and the scientists trying to rebuild (or upgrade) the human parts we lose. From stem-cell “hair nurseries” to xeno-pig organ farms, Roach uncovers the strange, brilliant future of becoming a “new” you.
