From the main points of views (Lilly and Sarah) you see how they switch lives, both being from seemingly mythical worlds, must be swapped to experience each others worlds, although Lilly had no idea what she was doing. And that's not the worse part. Because two mythical worlds have collided when they shouldn't have, another seemingly mythical world came out. The vampires have come out to earth and are looking for Lilly and Sarah. According to them, they must be punished for their crimes. Cover by: StarStruck29
