It's Just Not My Night!: Tale of a Fallen Vampire Queen

Powerful, world-conquering vampiress Manamir is on the verge of world conquest, but when a teleportation spell goes awry, she finds herself stranded on Earth. Not only has she been flung into a world that's not her own, she has lost the very power that defines a vampire: the ability to drink human blood! Unable to steal energy from others, Manamir has to make ends meet somehow, which is why she ends up working part-time at a convenience store, selling smokes to bikers while trying to grasp the subtleties of Earth life. Maybe she'd make more money selling her panties...
