Dangerous Obsession (Night Elves #2)
Nelissa Donovan

Charged as emissary of the Winter Kingdome, powerful shaman and shapeshifter Red Claw sets off to seek the aid of the other three Kingdomes. Yet his body and mind are fractured with needs he has worked to suppress for well over two centuries. Dangerous obsessions haunt him. Should he succumb to this desire, it could bring about a cataclysmic event foreseen in a prophetic vision during his first days in Tir n na-Og.
As Red Claw and Eristta battle inner and outer demons and their growing bond, they find a magic that can save their world…if they can learn to manage it. If they cannot, all may be lost.
