"William R. Forstchen is the master of real-world apocalyptic fiction, and his latest 48 Hours is a story that should be read by all--not just as a riveting piece of fiction but also as a cautionary tale of humanity at the edge. Here is a book that should be on everyone's shelf, a guidebook to the end of the world." --James Rollins, New York Times bestseller of The Demon Crown "When you're done with this one, you're going to ask yourself: Is this possible? Can it really happen? Here's the scary part. Not only can it happen, it already has, only this time it's going to be far, far worse. A surreal treat." --Steve Berry, New York Times bestselling author "When the sun blasts the earth with two life-extinguishing explosions of solar rays, humanity is suddenly brought to the brink of utter annihilation. What will we do? The reader will race through this stunning, electrifying novel all the way to its final, shocking conclusion and come back begging for more.

I'm definitely hoping for a sequel." --William S. Cohen, New York Times bestselling author and Former Secretary of Defense "[Forstchen's] best book to date. Fans of apocalyptic thrillers such as the movie Deep Impact will be engrossed." -- Publishers Weekly , starred review.
