“Documentarian Levitt sheds light on the tiniest bits of what humans are made of in his stellar debut… The author claims that ‘to retrace the journeys of our atoms is to appreciate the world anew,’ and his winning mix of astronomy, physics, biology, and chemistry will help readers do just that. This is marvelous.” 

– Publishers Weekly, *STARRED REVIEW*

“Writer and documentarian Levitt hits the ground running with news that a 150-pound human body contains 60 elements… To explain how they assembled into a human requires an explanation of life itself, which demands understanding the history of our planet. Many authors who write about our elemental makeup deliver this in an introductory chapter, but Levitt offers an entertaining history of the entire universe... [keeping] matters simple enough that science buffs will be satisfied and average readers will learn a great deal… Scientists have no idea how life began, but Levitt’s page-turning account emphasizes how quickly it happened: within a few hundred million years… [He] notes that the process of completing this book ‘has been a continual source of wonder, stupefaction, exhilaration, and gratitude.’ Readers will share those feelings. Lively, illuminating popular science.” 

– Kirkus

“A truly astonishing and eminently readable work of  chemical detection, provocative, surprising and alive with moments when you just want to tug your neighbor’s sleeve and ask - can you believe this?” 

– Simon Winchester, writer and editor, Lapham’s Quarterly

"Dan Levitt's "What's Gotten Into You" is one fascinating journey, from the fireworks of the Big Bang to the busy life of cells, this is a story of scientific discovery, history, dazzling egos, quiet courage, and pure unexpected insight. In other words, the best kind of story. Don't miss it." 

– Deborah Blum, Pulitzer-Prize winning author of THE POISONER'S HANDBOOK and THE POISON SQUAD
