A book dealer lies imprisoned in a Boston mansion, an IV tube dripping a lethal narcotic cocktail into his veins. In thirty-six hours, he'll be dead. His final request is to receive a visit from one woman....

It wasn't the most hospitable invitation she'd ever received. Archaeologist Annja Creed is being rushed to Massachussetts, abducted by a famous environmental terrorist--a zealot willing to kill anyone who gets in his or the planet's way. He has taken the book dealer hostage in order to steal a rare and very valuable treatise called the Tome of Prossos. Annja is the key to retrieving the ancient manuscript hidden somewhere deep within the mansion. But the book is well-protected. In order to find it, she must survive the rigors of an elaborate maze. She has only twelve hours to decipher the labyrinth's sinister secret...a secret that could ensure she never emerges.
