Incubus 1, Paperback/Brandon Varnell

Anthony Amasius likes to pretend he's nothing but a simple college student attending the Institution of Magical Sciences on Academy Island. The truth is that he's far from simple. Anthony is the only incubus in the entire world, though he refuses to bond with any woman. Right now his only goal in life is honoring the woman he loved and lost and bringing his younger brother out of a coma. But when a War Maiden from Custodes Daemonium comes knocking on his door with orders to kill him, Anthony will find himself being forced to make a choice: Embrace what he's become or die a dog's death.
