In 323 B.C.E, having conquered Persia, Alexander the Great set his sights on Arabia, then suddenly succumbed to a strange fever. Locating his final resting place - unknown to this day - remains a tantalizing goal for both archaeologists and treasure hunters. Now the quest for this coveted prize is about to heat up. And Cotton Malone - former U.S. Justice Department agent turned rare-book dealer - will be drawn into an intense geopolitical chess game. After narrowly escaping incineration in a devastating fire that consumes a Danish museum, Cotton learns from his friend, the beguiling adventurer Cassiopeia Vitt, that the blaze was neither an accident nor an isolated incident. As part of campaign of arson intended to mask a far more diabolical design, buildings across Europe are being devoured by infernos of unnatural strength.
