Annie Saves the Day (Magic Pony, No. 4)

It's been one of those days. First, Annie's snotty next-door neighbor almost guesses Annie's magic secret. Then, the neighborhood bullies show up. They want her brother's new bike helmet--and they'll do whatever it takes to get it! Now Annie has to find her brother--before the bullies do. Can Annie and her magic pony beat the bullies, rescue the helmet, and save the day?
