Born of Saint & Sin

When Angelic -the daughter of Saint Lucifer- escapes her father and flees the underworld, she meets an unlikely companion, Kitty. Although Kitty too -like Angel- is no human. This badass vampire chick also is on the run, and together they face enemies from both the dark AND light sides of myth on their journey to save humanity from their oblivious destruction.
