Dream-Shifter

12-Year-Old Gwendolyn is a Dream-Shifter. She Becomes the Animals She Dreams About.

When she wakes normally, she becomes human again. But just as she's leaping around as an elk, a fire alarm jars her awake. It's elk hunting season, and she doesn't know how to change back to a girl, or how to stay alive. But she still speaks English, and she still thinks like a girl. The thing she wants most is to attend journalism camp. The camp only admits humans. She goes to the magician for help. He gives her access to his magical library, and trains her to put on magic shows.
He does have a book that might help, but there's a spell on the book, so she can't get near it.

Will Gwendolyn spend the rest of her life as an elk?
