When Heidi finds out about a magical wishing well at her school, she's amazed and delighted--even though students are forbidden to use it. Then, an important exam is scheduled at the very same time her crush invites her on a nature walk, and Heidi needs a magical assist. Usually, she tries to follow the rules--really!--but she decides to use the well to wish to be in two places at once. What could go wrong?
