“Before You Spit in That Vial, Read This Book.”
— New York Times

“[The Lost Family] wrestles with some of the biggest questions in life: Who are we? What is family? Are we defined by nature, nurture or both?”
— The Washington Post

“A fascinating account of lives dramatically affected by genetic sleuthing.”
— The Wall Street Journal

“Copeland takes readers inside America’s first DNA testing lab dedicated to genealogy, to Salt Lake City’s Family History Library—the largest genealogical research facility in the world—and into the living rooms of dozens of people whose lives have been turned upside down due to the results of a recreational DNA test. It is at once a hard look at the forces behind a historical mass reckoning that is happening all across America, and an intimate portrait of the people living it.“

“The Lost Family is a fascinating exploration of the mysteries ignited by DNA genealogy testing—from the intensely personal and concrete to the existential and unsolvable. In the world Copeland's 'seekers' are exploring, 'Who am I?' becomes a mystery more intricate and more crucial than any novel's 'Whodunit?' Copeland deftly weaves together individual stories, technical explanations and sociological discussion to make a book that's both gripping and deeply thought-provoking.”
— Tana French

“So many families have been touched—and will continue to be touched—by the secrets unearthed by home genetic testing. We are in an epidemic with few signposts, little to guide us as we contend with the unintended consequences brought upon us by scientific advancement. The Lost Family is an urgently necessary, powerful book that addresses one of the most complex social and bioethical issues of our time.”
— Dani Shapiro

"Not long ago, the idea of sequencing your DNA was as plausible as booking a trip to Jupiter. Now we give each other DNA tests as holiday gifts. As tens of millions of people look at their genes and link them to their ancestry, this science is having a profound impact on our society as a whole. It is reuniting relatives, breaking up families, and sending criminals to jail. The Lost Family is a deeply reported, deeply humane exploration of our ongoing redefinition of our identity and our kinships."
— Carl Zimmer

"A compellingly readable narrative that takes us down the rabbit hole of modern personal genomics. Libby Copeland brings a gripping story from the front lines of genealogy and genomics."
— Razib Khan
