Being An Assassin...And A Hero

Derreck is a just fifteen when his dad is killed in a car wreck and his mother is left in a coma from the same thing. A year later he finds out he can shift into a cat. Years pass as he hides it from everyone until he is approached to become an enforcer for the council. On his first assignment he finds his mate, but has to kill her father. When she rejects him, he leaves, but what happens when he comes back five years later...with his second chance mate? And what will he do when his little sister finds her own mate in his ex-mates werewolf pack? Decision must be made and Derreck is about to be caught up in a conspiracy larger than the rogues he's used to killing as an enforcer.
