Oppenheimer’s Demon

Hiroshima, Nagasaki… Chicago?
Everyone knows about the two atomic bombs dropped on Japan in 1945. But Robert Oppenheimer’s Manhattan Project had on hand another nuclear core. After claiming the lives of two scientists in separate accidents, it was dubbed the Demon Core and melted down. Some demons, however, are not so easily destroyed. And now Chicago DA Glenn Winders finds himself in a race against the clock to stop a shadowy nuclear terrorist and prevent World War III. His city is descending into panic, his teenage daughter is swept up in the chaos, and his only hope is a beautiful neurosurgeon whose controversial beliefs pose a challenge all their own.

Praise for Geoffrey Simmons

For Oppenheimer’s Demon

No author should be allowed to be as multitalented as Geoffrey Simmons. A distinguished physician. A successful novelist with both medical thrillers and comic novels to his name. A leading disaster preparedness expert. The author of two razor-sharp critiques of modern evolutionary theory, Billions of Missing Links and What Darwin Didn’t Know. Now Simmons has masterfully combined his multifaceted array of gifts, experiences, and training. Oppenheimer’s Demon is a riveting disaster thriller in which both the origin and end of man hang in the balance. Bravo!
