Soraya is a creative girl who marches to the beat of her own drum. She feels isolated from her fourth grade classmates and is most comfortable in the world of her comic book hero, Nimbla Moony. A class trip to the aquarium yields an unexpected surprise when Soraya is approached by a young mermaid who needs help returning to the sea. How can Soraya get Estelle safely out of the building to the nearby bay without detection? Does she have what it takes to be brave like her hero? Alikhan offers a fresh take on contemporary fantasy for the chapter book set with this diverse cast of characters, perfect for kids who struggle with fitting in with their peers. Soraya finally connects with a friend who accepts her quirks. Estelle can certainly relate, since her STEM-focused desire to design underwater buildings is atypical mermaid behavior. By the book's end, Soraya starts to learn to love herself and to trust others, as she and Estelle must accept help from various sea creatures to pull off the escape.
