The Oppenheimer Alternative Robert Sawyer

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 weapon 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 physicists combine forces with Albert Einstein, computing pioneer John von Neumann, and rocket designer Wernher von Braun — 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.
