"This is some good shit, people. Not only entertaining, but deeply important. Everyone with a colon should read this book. Centuries back, people knew the value of shit. In countries with poor soil, human waste was like gold: people stole it, paid their rent with it, and gave it as gifts. Today, keeping it out of our waterways is our best hope for defusing what Zeldovich calls the Great Sewage Time Bomb. She is an ideal guide to this ridiculously fascinating world."-- Mary Roach, author of Stiff: The Curious Lives of Human Cadavers
"Zeldovich shows to dazzling effect how a famously difficult subject—the often peculiar scientific history of human waste—can become an engrossing tale. The story is enlightening, surprising, occasionally enraging—and wholly worth your time."-- Deborah Blum, Pulitzer Prize–winning author of The Poison Squad
