Mermaid school

"It's Marnie Blue's first day at Lady Sealia Foam's Mermaid School, and she's terrified. What if she can't make friends? What if she has to ride a seahorse? And what if the teachers assume she's just like her Aunt Christabel, a famous singer who was a troublemaker growing up. Even though Marnie is sweet and tries her best to fit in, a mermaid named Orla seems intent on getting her in trouble. But when Orla finds herself in danger, Marnie has to swim to the rescue"--Publisher provided.
