From the New York Times best-selling author of Stiff and Fuzz, a rollicking exploration of the quest to re-create the impossible complexities of human anatomy. The body is the most complex machine in the world, and the only one for which you cannot get a replacement part from the manufacturer. For centuries, medicine has reached for what’s available—sculpting noses from brass, borrowing skin from frogs and hearts from pigs, crafting eye parts from jet canopies and breasts from petroleum by-products. Today we’re attempting to grow body parts from scratch using stem cells and 3D printers. How are we doing? Are we there yet? In Replaceable You, Mary Roach explores the remarkable advances and difficult questions prompted by the human body’s failings. When and how does a person decide they’d be better off with a prosthetic than their existing limb? Can a donated heart be made to beat forever? Can an intestine provide a workable substitute for a vagina? Roach dives in with her characteristic verve and infectious wit. Her travels take her to the OR at a legendary burn unit in Boston, a “superclean” xeno-pigsty in China, and a stem cell “hair nursery” in the San Diego tech hub. She talks with researchers and surgeons, amputees and ostomates, printers of kidneys and designers of wearable organs. She spends time in a working iron lung from the 1950s, stays up all night with recovery techs as they disassemble and reassemble a tissue donor, and travels across Mongolia with the cataract surgeons of Orbis International. Irrepressible and accessible, Replaceable You immerses readers in the wondrous, improbable, and surreal quest to build a new you.

A devastating love story. A bewitching twist on history. A blood-drenched hunt for purpose, power, and redemption. In 1785, Professor Sebastian Grave receives the news he fears most: the terrible Beast of Gévaudan has returned, and the French countryside runs red in its wake. Sebastian knows the Beast. A monster-slayer with centuries of experience, he joined the hunt for the creature twenty years ago and watched it slaughter its way through a long and bloody winter. Even with the help of his indwelling demon, Sarmodel – who takes payment in living hearts – it nearly cost him his life to bring the monster down. Now, two decades later, Sebastian has been recalled to the hunt by Antoine Avenel d’Ocerne, an estranged lover who shares a dark history with the Beast and a terrible secret with Sebastian. Drawn by both the chance to finish the Beast for good and the promise of a reconciliation with Antoine, Sebastian cannot refuse. But Gévaudan is not as he remembers it, and Sebastian’s unfinished business is everywhere he looks. Years of misery have driven the people to desperation, and France teeters on the edge of revolution. Sebastian’s arcane activities – not to mention his demonic counterpart – have also attracted the inquisitorial eye of the French clergy. And the Beast is poised to close his jaws around them all and plunge the continent into war. Debut author Cameron Sullivan tears the heart out of history with this darkly entertaining retelling of the hunt for the Beast of Gévaudan. Lifting the veil on the hidden world behind our own, it reimagines the story of Europe, from Imperial Rome to Saint Jehanne d’Arc, the madness of Gilles de Rais and the first flickers of the French Revolution.
