Friendship, worries, and newfound courage all play a part in this underwater tale of a tiny mermaid heroine.

"I'll always be here; there's no need to fear. All will be well when a pond mermaid's near."

Lily the pond mermaid loves taking care of her pond and all the creatures that call it home. But it's also a big responsibility. Lily often worries about not being able to keep the pond-and everyone in it-safe. As her worries grow, a big storm hits the pond, and everything becomes covered in a tangle of debris. Luckily, Lily is able to share her feelings with her friends and ask for help. Together, Lily and the animals that live in the pond not only restore their home but also learn how to take care of one another.
