A brother's vow. A lover's promise. Both could put them all at deadly risk.

Remington Lassiter is trying his best to stay out of trouble while he learns the ropes of being a werewolf. When his little brother turns up covered in bruises, he is driven to finally bring their abusive father to justice.

Jake Romero, a crack private investigator with a bad-boy biker image, realizes he has his work cut out for him when Remi asks for his help. From the first moment he turned Remi into a werewolf in order to save his life, Jake has been fighting to keep his inner demons at bay. He's torn between the desire to tell Remi they are destined to be mates, and the need to first let Remi get used to the werewolf life.

Jake will do anything to protect Remi and help him break the cycle of abuse he has endured all his life, but his investigation is about to uncover something far more sinister and deadly than they ever imagined.
