J. Robert Oppenheimer: reluctant father of the atomic bomb, enthusiastic lover of books, devoted husband and philanderer. Engaging with the books he voraciously read, and especially the Bhagavad Gita, his moral compass, this lyrical novel takes us through his story, from his tumultuous youth to his marriage with a radical communist and the two secret, consuming affairs he carried on, all the while bringing us deep inside the mind of the man behind the Manhattan Project. With the stunning backdrop of Los Alamos, New Mexico, Oppenheimer's spiritual home, and using progressively shorter chapters that shape into an inward spiral, Y brings us deep inside the passions and moral qualms of this man with pacifist, communist leanings as he created and tested the world's first weapon of mass destruction -- and, in the process, changed the world we live in immeasurably.
