Mighty warriors sworn to protect humanity, the shape-shifters known as The Shadowmen move between two worlds. Now their dark leader has exiled himself from the spirit world, opening the door to the forces of chaos...and to the power of love. Half wolf, half man, Aragon has abandoned his brethren to repay a debt of honor; he is sworn to kill a rogue Blood Hunter, though exacting revenge will doom him to a ghostly existence trapped between two worlds. But when a mortal woman unexpectedly calls him to her side, the heat of her soft flesh arouses a hunger in him that threatens to complicate his mission. Dr. Annette Batista, a dedicated healer, is determined to find her missing sister. With the amulet found at the site of her sister's disappearance, she unwittingly summons a shadowy warrior. She wonders if she can trust this powerful male named Aragon, who claims he can vanquish her sister's captor -- the very monster he's vowed to destroy. Or is Annette blinded by her shocking passion for the most alluring, mysterious man she's ever seen?
