Stolen (Women of the Otherworld, #2)

In Stolen, on a mission for her own elite pack, she is lured into the net of ruthless Internet billionaire Tyrone Winsloe, who has funded a bogus scientific investigation of the "other races" and their supernatural powers. Kidnapped and studied in his underground lab deep in the Maine woods, these paranormals - witches, vampires, shamans, werewolves - are then released and hunted to the death in a real-world video game. But when Winsloe captures Elena, he finally meets his match.
