They say demons and angels don't mix. I say people should mind their own damn business.My brother, Damian, has been my rock ever since mom left. Didn't matter to him that I was a lowly half-demon while angel blood flowed through his veins. I was his and he was mine.But nothing lasts forever.He wants me to go to college. I'd rather fight a hundred sentinels than lead a boring, safe life hiding who I am. So when a nephilim goes missing, I go behind Damian's back to find the teen. Maybe if I can solve the case, he will upgrade me to his partner in crime solving.As bodies begin to drop, I realize I'm in way over my head. But there's no way I'm going to admit that, not when my future hangs in the balance. Instead, I set my eyes on recruiting the help of the new kid. Lucas is arrogant, sexy, and persistently trying to get my number. He's also a nephilim. Off-limits, no matter how good he looks flinging fireballs.Then again, I was never good at resisting temptation.
