Elena Michaels is a 21st-century girl: self-assured, keenly intelligent, fighting fit. And like every woman, she has her secrets. Nothing extraordinary about that. Except that Elena really is extraordinary. In fact, she may well be the most extraordinary woman alive. Because Elena is the only female werewolf in the world . . .Ten years ago, against her will, Elena's lover turned her into a werewolf. Some days it feels like a gift. Most days it feels like a curse. A year ago, she decided to leave the protection of the Pack - her wolf family - to live as a human. But now the Pack is under siege by a new group of werewolves who show no respect for the old ways, and who kill indiscriminately. Elena must use all her powers to hunt and detroy the renegade pack before they destroy her. But in doing so, will she lose her human side completely? It's time to decide where her loyalties lie.
