My fangtastically evil vampire pet

The Great and Powerful Mark is going to Evil Scientist Summer Camp where there are no annoying little brothers and no annoying zombie goldfish. Just Mark, his best friend Sanj, their notebook of evil plans, and his truly evil and forbidden vampire kitten Fang. But he didn't expect for the totally not-evil Geeky Girl to show up, or for Sanj to find a new partner to work with. But there's no way he's going to let them ruin his summer.
