Oona loves to share her inventions with her friends. They’re big and bold and LOUD—just like her! But there’s one underwater creature who doesn’t seem to enjoy Oona’s company, or her creations. Stanley the shark doesn’t care for her squeaky unicorn. And he’s far too busy for the Sea Horse Carousal. And Oona’s latest hopping, chopping, and popping inventions just make him angry. Oona may not know what Stanley likes, but she does know what he doesn’t. And maybe that’s a good place to start. Because mermaids never stop trying…not when there’s a friend out there to make. This next underwater adventure from New York Times bestselling author Kelly DiPucchio and artist Raissa Figueroa is a heartwarming tale about the unexpected ways in which friendships can form—even between a tiny mermaid and a hammerhead shark.
