Jen is a child advocate, burdened by a tragic past. When she's called in for a little boy discovered, alive but suffering amnesia, in the midst of a massacre involving attack dogs, little does she know her life has taken a turn into the shadowy society of the wolves. Adrien is Tragen's Enforcer—the police force, judge, jury, and executioner of the local pack. From the moment he hears the news reports, he knows he'll soon be hunting his own for endangering the peace between wolf and human. But nothing could have prepared him for Jen, the daughter of Andrew "Lion" Verik. Or for the fact that the young survivor is not only a wolf but also a Keif, the future leader of the pack. A Keif sees the future, as if it was fact, but his enemies will stop at nothing to kill him before he can take power, even if it means going through Jen and Adrien to do it.

More than seven years have passed. Keif is an adolescent wolf, and the twin boys are a handful of trouble. It's Christmas in Jen and Adrien's cabin, and though wolves don't usually celebrate the human holiday, the entire den has embraced the alpha female's traditions. But all is not calm in the den. Can Keif ease tensions with a special surprise?
