Summary: Castiel’s true mate, Michael, has been on the run from the law for the last couple of years. He didn’t treat Castiel well, even when they had been together, so Castiel is relieved that their bond is broken, even though it leaves him with a feeling of loss and longing for something he can’t quite put his finger on. Still, he has no intention of finding a new mate since he has a hard time trusting alphas as well as his own nose.
Enter undercover cop Dean, who is on Michael’s case and tries to find out what Cas knows about his true mate’s whereabouts.
The mutual attraction is immediate, but with Cas’ past and Dean’s secrets neither of them have any idea what they’re in for.
