She-Devil: Blackwater Sorcerers #1
Angelica Wang's body was found dead in a creek the morning after her Sweet Sixteen. While the town of Saint-Eau mourns the tragic loss of this beautiful young human girl, Saylor parties with her fellow sorcerer friends and learns to make pacts with demons at Blackwater University. But then, things get grimer when angels start invading the town and looking to exorcise all demons and sorcerers in their paths.
