My Sister the Vampire #1: Switched

Imagine finding out that you have a twin sister¿and she¿s a vampire! That¿s what happens to chipper cheerleader Olivia when she moves to Franklin Grove and meets Ivy, an ultra-goth girl who looks strangely familiar. The girls discover that they were both adopted, both have identical rings given to them by their birth parents, and they were both born on the same day, in the same town. They¿re twins! They decide to switch places for an afternoon, swapping clothes and trying on each other¿s attitudes. Switching places should be no problem! Except, there is one other difference: Ivy is a vampire!
