The Armageddon Box by Robert Weinberg The sequel to The Devil’s Auction.
A friend’s brutal murder brought the seemingly worthless book into Alex Warner’s possession. He had no idea that it held the secret to an age-old mystery and key to unimaginable power. But he discovered that quick enough as he found himself the target of a secret religious cult and a strange Neo-Nazi superman with incredible powers. With Valerie Lancaster, Alex must follow the trail of the book from Chicago’s back alleys to an impregnable Swiss fortress, and learn the hidden history of an ancient race of vampires and their ties with Nazi Germany. Only then would he learn how to open the Armageddon Box.
