About This Book
Nobody in Oak Grove likes water, but Eel and Trout don’t just like it—they live for it, with their unusual tastes and fish-like speed. When a flood traps them at home, they discover a secret that changes everything: they’re the sons of a mermaid. This surprise turns their world upside down and shows why being different can be a superpower.
