My name is Emily Fairchild and in all my sixteen years I never imagined that magic was real. That is, until my best friend discovered a mysterious notebook filled with runes and magic spells, and the most popular girl in school turned out to be a real-life witch. As a result of a horrible magical accident, we’re now stuck with a six-thousand-year-old demon who acts like a teenage boy with a really bad attitude and is trapped in our dimension. And somehow it’s all my fault. So, until we figure out how to get rid of him, I have to babysit a demon who now lives in my room, reads my diary, eats all my food, and stalks blonde underwear models online. How did my life ever get so complicated?
