New York Times bestselling author Kelly DiPucchio and Coretta Scott King Illustrator Award winner Raissa Figueroa are back with another gorgeous and grand tale from the big sea’s littlest mischief-maker, Oona!

Oona is on a mission! A baby beluga whale has lost her way from her family and needs help getting back to her icy arctic home!

But Oona and her best friend Otto have never traveled from their warm ocean waters before. Will old ship maps and a compass be enough to lead them through the dangerous storms ahead?

Oona may be a little mermaid, but she is determined to see this big adventure through! With a bit of bravery and help from some new friends, they'll do all they can to reunite this baby whale with her pod once more.

As School Library Journal said of the first book in this series, Oona: “This title celebrates independence, self-confidence, and bravery to try the new even after defeat as Oona becomes aware of the true treasure in her personal effort.”
