Not a unicorn

Summary/Review: Eighth-grader Jewel has all the usual middle school problems (crush on an unattainable boy, ex-BFF), but the thing that is making life a torment at school is the horn growing out of her forehead, which cannot be removed simply; she has two friends she can depend on and an invisible unicorn companion, but she would really like to be normal in time to read her essay in regional French speaking competition--and maybe she has found a doctor who can do it, but there will be consequences to face.
