Angels and vampires are real. In the world of the Asuune, half angel and half human, there is a secret war that has been going on for as long as man has walked the earth. Unbeknownst to Kathrine, her father is one of the war's soldiers but what is even more surprising is that she is the war's only hope. Follow the life of Kathrine Albet and her father, Mark, as they fight the evil of fallen angels and vampires to save humanity. It would all be much easier if each Asuune didn't have one true love they couldn't ignore. Fighting the forces of evil may be hard but resisting your true love is all but impossible.
