Undead And Unappreciated

Undead shopaholic Betsy Taylor has found that being vampire queen has more problems than perks. It may be easy to find blood in the dark of night, but try finding a strawberry smoothie. And employees at her nightclub Scratch have been giving her nothing but grief since she killed their former boss. Some people... But Betsy's "life" takes an interesting turn at a baby shower for her wicked stepmother, who lets it slip that Betsy has a long-lost half sister.
Now twenty years old, this girl just so happens to be the devil's daughter and destined to rule the world.
