New York Times bestselling author Kelly DiPucchio teams up with illustrator Raissa Figueroa for a delightfully humorous picture book starring a mischievous black mermaid, her sea creature friends, and their surprising finds during their quest for treasure. 

Meet Oona. The big sea’s littlest mischief maker.

She and her best friend, Otto, love to search for treasure . . . but often find trouble instead.

Messy trouble.

Tricky trouble.

Even shark-related trouble.

That’s never stopped them before, though!

After all, no proper treasure hunt is without some adventure. But when the grandest treasure yet is stuck in a deep, dark rift, Oona’s not sure if she can dive right in. What might be waiting for her in those unknown waters?

With gorgeous underwater scenes from rising new talent Raissa Figueroa and humor and heart abounding in New York Times bestselling author Kelly DiPucchio’s text, this little mermaid’s tale is a celebration of friendship, creativity, and bravery in the face of the unknown.
