A detective with a secret lineage. An undercover Hunter with a bullet-proof soul. And a world made to pay for the sins of an angel... Homicide detective Alexandra Jarvis answers to no one. Especially not to the new partner assigned to her in the middle of a gruesome serial killer case-a partner who is obstructive, irritatingly magnetic, and arrogant as hell. Aramael is a Power--a hunter of the Fallen Angels.  A millennium ago, he sentenced his own brother to eternal exile for crimes against humanity. Now his brother is back and wreaking murderous havoc in the mortal realm. To find him, Aramael must play second to a human police officer who wants nothing to do with him and whose very bloodline threatens both his mission and his soul.   Now, faced with a fallen angel hell-bent on triggering the apocalypse, Alex and Aramael have no choice but to join forces, because only together can they stop the end of days.
