What’s to be done about a jaywalking moose? A bear caught breaking and entering? A murderous tree? Three hundred years ago, animals that broke the law would be assigned legal representation and put on trial. These days, as New York Times best-selling author Mary Roach discovers, the answers are best found not in jurisprudence but in science: the curious science of human-wildlife conflict, a discipline at the crossroads of human behavior and wildlife biology.

Best-selling author Mary Roach returns with a new adventure to the invisible realm we carry around inside. Roach takes us down the hatch on an unforgettable tour. The alimentary canal is classic Mary Roach terrain: The questions explored in Gulp are as taboo, in their way, as the cadavers in Stiff and every bit as surreal as the universe of zero gravity explored in Packing for Mars. Why is crunchy food so appealing? Why is it so hard to find words for flavors and smells? Why doesn’t the stomach digest itself? How much can you eat before your stomach bursts?

For two thousand years, cadavers have been involved in science's boldest strides and weirdest undertakings. They've tested France's first guillotines, ridden the NASA Space Shuttle, been crucified in a Parisian laboratory to test the authenticity of the Shroud of Turin, and helped solve the mystery of TWA Flight 800. For every new surgical procedure, from heart transplants to gender reassignment surgery, cadavers have been there alongside surgeons, making history in their quiet way.

In an attempt to find out, Mary Roach brings her tireless curiosity to bear on an array of contemporary and historical soul-searchers: scientists, schemers, engineers, mediums, all trying to prove (or disprove) that life goes on after we die. She begins the journey in rural India with a reincarnation researcher and ends up in a University of Virginia operating room where cardiologists have installed equipment near the ceiling to study out-of-body near-death experiences.

Follow New York Times best-selling author Mary Roach - but be careful not to trip - as she weaves through personal anecdotes and everyday musings riddled with her uncanny wit and amazingly analytical eye. These essays, which found a well-deserved home within the pages of Reader's Digest as the column "My Planet," detail the inner workings of hypochondriacs, hoarders, and compulsive cheapskates. (Did we mention neurotic interior designers and professional list makers?) For Roach, humor is hidden in the most unlikely places, which means that nothing is off limits.
