Ethan loves lemon cookies, lemon cupcakes, and even slices of lemons. But he doesn’t realize he receives magical powers from food that makes him pucker. When his best friend, Luke, mentions he wishes he could fly, Ethan—having just eaten lemons—waves his arms, and whoosh, Luke flies overhead like a bird. Much to his surprise, a wide-eyed Ethan watches Luke glide above the swing set, hover over their special tree house, and make figure eights in the sky. After the initial fun and excitement, Ethan begins to worry. How will he get his friend back on the ground? Will Ethan regain his super powers or will Luke fly in the sky forever?
