Stella Batts by Courtney Sheinmel

Book Description:
One of the best things about having parents who own a candy store is getting to be an official taste-tester. When her dad brings home Magical Glow-in-the-Dark Chewing Gum, Stella can t wait to try it out especially since her younger sister is already blowing bubbles and making magic-gum wishes that come true. Except the gum seems to bring Stella bad luck. First she can t even blow a bubble, then she falls asleep chewing a piece of gum that ends up wadded in her hair, resulting in a drastic haircut. And now her best friend, Willa, announces she s moving clear across the country! It s hard to believe in any kind of magic when stuff like this happens. But Stella knows that when the going gets tough, the tough get going and that s exactly what she plans to do.
