"A woman stands by the side of the road, barefoot and bleeding, a child in her arms. Someone just tried to kill her, but she wouldn't recognize him if she saw his face. She doesn't remember her own name. A suburban cop surveys a kitchen in disarray--a woman and child missing, a chilling note. The man who calls himself Gideon waits and plans. He sees himself as a destroyer of evil, one who rids the world of abominations. He has already killed five. He will kill again. And somewhere in the wilderness, in a secret geocache near where the wild swans gather, lies the unspeakable clue that links them all together."--Page 4 of cover.
