Writing with “a sense of wonder that hasn’t prevailed since the days of Heinlein” (Books in Canada), best-novel Hugo and Nebula Award-winner Robert J. Sawyer brings you “a truly science-fictional work of alternate history” (S.M. Stirling).

While J. Robert Oppenheimer and his Manhattan Project team struggle to develop the A-bomb, Edward Teller wants something even more devastating: a bomb based on nuclear fusion — the mechanism that powers the sun. But Teller’s research leads to a terrifying discovery: by the year 2030, the sun will eject its outermost layer, destroying the entire inner solar system — including Earth.

After the war ends, Oppenheimer’s team plus Albert Einstein and Wernher von Braun stay together — the greatest scientific geniuses from the last century racing against time to save our future.

Meticulously researched and replete with real-life characters and events, The Oppenheimer Alternative is a breathtaking adventure through both real and alternate history.

“I loved it!” —Lee Smolin, author of The Trouble with Physics

“An imaginative restructuring of a phantasmagoric life into an alternative phantasmagorical story. Oppenheimer fans will be intrigued.” —Martin J. Sherwin, co-author of American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer

“Really great, a page-turner; I was hooked from the beginning to the end. Another fine addition to the Sawyer canon!” —Andre Bormanis, co-executive producer, The Orville and Cosmos: A Spacetime Odyssey

“Incredibly realistic: the characters, locations, the era, and even the science. I felt like I was back in Los Alamos — and I should know: I worked there! Breathlessly riveting; Sawyer pulls it off masterfully.” —Doug Beason, former Associate Laboratory Director, Los Alamos National Laboratory

“I knew many of these physicists, and Sawyer nails them accurately.” —Gregory Benford, author of The Berlin Project

“My favorite Sawyer book of all; a solid award contender!” —Amazing Stories

“Science fiction fans will devour this smart speculative tale.” —Publishers Weekly

“This book has everything a reader wants from Sawyer.” —Analog
