“America's most quoted bioethicist has written the definitive guide to the international consensus against germline editing... and how it all came crashing down in November 2018. In a concise retelling that's part diary, part history, and part journalism, Hank Greely pieces together how a Chinese scientist defied bioethics—and common sense—to create the first gene-edited humans."

Antonio Regaladobiomedicine editor, MIT Technology Review

“Hank Greely is a master of detail, and delivers an 'as if you were there' portrayal of events surrounding the announcement of the first children born with edited genomes. For anyone who wants to know how we got there, and where we go next, this is the book for you. With both nuance and wit, Greely makes you an expert, too."

R. Alta CharoWarren P. Knowles Professor of Law, University of Wisconsin–Madison

“Hank Greely, a renowned authority on science and law, delves deeply into the complex, evolving world of human germline genome editing, offering a story rich in scientific fact, but also a fascinating portrayal of key players, critical turning points, and the promise and peril of this scientific advance."
