Ashes and Angel Wings (Trilogy of the Fallen) by Greg Stolze

Hell to Pay

The gates of Hell have cracked and demons have escaped to walk the earth, dressed in human flesh. But when the ancient Scourge Hasmed finds himself in the body of three-time loser and mob bagman Harvey Ciullo, he finds the world a very different place than he expected. Using his demonic will, he begins to claw his way up the New Jersey underworld, determined to make it his own.

The Angelic Host that locked him away seems to have vanished, but other demons are out there. And all the while, this hardened child of the pit can't quite shake his affection for Harvey's daughter, an instinct that could redeem his soul or destroy him forever.
