I get an early birthday present

What is lurking in the shadows? Monsters? Animals? Or you?
Elizabeth Lee has been teased as long as she can remember, for many different things. Living in an orphanage , never meeting her parents, and seeing strange things. When she was little her problems weren't that bad but now that she is almost thirteen strange things are happening. She finds strange warnings everywhere. She sees large unidentifiable creatures in the woods. She hears a small voice in her head telling her to do things that make absolutely no sense. She sees her reflection everywhere she goes. But on October 30th, her 13th birthday everything she had ever known will change.
