Shapeshifter Xander will remain stuck in oblivion between good and evil until he is marked--either with the sphere that will identify him as a servant of the underworld or with the water mark, serving the keepers of humans, vampires, and warlocks. One decision will mark him and his twin sister Mira equally. She is in love with a man bearing the water mark and wants Xander to follow the path of the good. But Xander loves a black witch, a minion of the underworld. All he has to do to join her forever is kill. After all, there's something good about being bad.
