Sixteen-year-old Vivian Gandillon is trying to fit in to her new home in the suburbs, which isn't easy since she and her family are werewolves. When she falls in love with a human, she must sort out her loyalties.
Vivian Gandillon relishes the change, the sweet, fierce ache that carries her from girl to wolf. At sixteen, she is beautiful and strong, and all the young wolves are on her tail. But Vivian still grieves for her dead father; her pack remains leaderless and in disarray, and she feels lost in the suburbs of Maryland. She longs for a normal life. But what is normal for a werewolf?

Then Vivian falls in love with a human, a meat-boy. Aiden is kind and gentle, a welcome relief from the squabbling pack. He's fascinated by magic, and Vivian longs to reveal herself to him. Surely he would understand her and delight in the wonder of her dual nature, not fear her as an ordinary human would.

Vivian's divided loyalties are strained further when a brutal murder threatens to expose the pack. Moving between two worlds, she does not seem to belong in either. What is she really--human or beast? Which tastes sweeter--blood or chocolate?
