On October 31, 2001, Edward Carnby's partner Charles Fiske is found dead near the mysterious Shadow Island off Massachusetts. The trail leads to three ancient tablets of incredible and dangerous power. Joined by the sharp university professor Aline Cedrac, Carnby makes for Shadow Island to pick up where Fiske left off — and their plane is attacked before they even arrive. The investigation begins in the forests and rooftops of a remote island manor.
