On the 75th anniversary of the dropping of the atomic bomb, Hugo and Nebula-winning author Robert J. Sawyer takes us back in time to revisit history…with a twist.

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.

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.

As the war ends with the use of fission bombs against Japan, 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
