BOOK6   RedemptionBook Six of the "It's In The Blood" Series (Rise of the Werewolf)Redemption isn't a destination. It's a choice made every day... for the rest of forever. For decades, Angel Coleman has hidden a predator's soul behind the innocent face of a ten-year-old boy. He has done unspeakable things in the name of his bloodline, but for the first time in his thirty-nine years, he wants to be something he never thought possible: Good.
As young Michael Hall approaches his thirteenth birthday-the threshold of a transformation that will bind him to the vampire world forever-Angel stands as his unlikely protector. But the path to the light is blocked by the ghosts of Angel's past. The ancient evil of Miguel Sanchez still whispers in the shadows, but a new, older presence has emerged. Something has been waiting centuries for the child Debbie Anderson is carrying-Angel's unborn son.
A hybrid whose very existence defies the laws of nature and threatens to ignite a war between species. In a world of "Death Wishes" and ancestral curses, Angel must fight to protect the boy he once hunted and the son he hasn't yet met. To save his family, he must finally confront the monster in the mirror and prove that even a soul born in darkness can find its way home.
