Kiss of Snow (Psy-changeling Series) Reprint edition

Since her defection from the PsyNet and into the SnowDancer wolf pack, Sienna Lauren has had one weakness: Hawke. Alpha and dangerous, he lost the woman who would've been his mate long ago. Now he walks alone. But Sienna stirs his primal heart, even as he tells himself she is far too young to handle the wild fury of the wolf. Yet as they strip away each other's secrets, a deadly enemy is striking at everything the pack holds dear...but Sienna's darkest secret may savage the pack that is her home-and the alpha who is its heartbeat.
