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 Massachusetts, 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.
