Turned

Gwen is back with the Twelve, but she must redeem herself to the others and, more importantly, Lucifer himself. In order to prove herself, she must capture Berlin and Moscow, but there is a problem-there are still two Gargoyles left to destroy and they still have Collin, a half-demon, half-human who has the same powers as the demons.
