“A truly science fictional work of alternate history which turns on the decisions―and discoveries―of the great physicists who wrote the history of the 20th century: Einstein, Fermi, Gödel, and Oppenheimer. They are the vividly realized, all-too-human characters who people this novel, and give its brilliant speculations human life and blood. Bravo!”―S.M. Stirling, author of Dies The Fire

Breathlessly riveting; Sawyer pulls it off masterfully.”―Doug Beason, former Associate Laboratory Director, Los Alamos National Laboratory “The feel and detail of the Manhattan Project figures is deep and well done. I knew many of these physicists, and Sawyer nails them accurately.”―Gregory Benford, author of The Berlin Project

“Sawyer portrays brilliantly and poignantly the struggles of the scientists who started it all and were consequently obliged to bear an unbearable burden.”―James Christie, Chair, Project Ploughshares, member organization of the Nobel Peace Prize-winning International Campaign to Abolish Nuclear Weapons

“Sawyer has outdone himself! No one could have taken on this project with such gusto and with such a search for the truth as this outstanding author. I’ve never read such a complete and thrilling account of Oppenheimer’s world.―Jonas Saul, author of the Sarah Roberts series
