My Sister The Vampire; Switched by Sienna Mercer

                      Switched is kind of based on the ABC show Switched At Birth. But the first main character in the book, Olivia Abbott, moves to town, now is excited to go to Franklin Grove Middle School, and is excited to join the cheer team. Then she meets Ivy Vega. At first Ivy is more goth and Olivia is more of like the opposite of her, dresses more perky, so they're not exactly the same. When the two sisters meet at school, they decide to get know each other, then they discover they're identical twins and separated at birth! But were adopted by different parents. Olivia couldn't decide the fact that she had a sister or a twin sister.
                    Olivia and Ivy both brim with plans to switch places with each other so that Ivy would be Olivia and Olivia would be Ivy to trick people in there school. But Ivy never believed it would work until they have fallen for it. Sooner or later Ivy had to tell Olivia...that she was a vampire. At first, Olivia didn't believe until she found out that Ivy was allergic to garlic and hated sunlight. But Ivy wasn't the only one that was a vampire at Franklin Grove, ivy's best friend Sophia was a vampire also and the other goths that Ivy hangs out with. Olivia had believed all of that and couldn't tell anyone. But she had no choice but tell Sophia that Ivy told her that most of them were vampires, Ivy found out, so Ivy and Olivia made a twin pact that they would never keep secrets from each other and pledge to stick together as SISTERS.
