Oona is one determined little mermaid, but she faces her biggest challenge yet in trying to make friends with Stanley the shark. Whatever will she do? A fun-filled and gorgeously illustrated celebration of friendship, creativity and perseverance.

Oona loves to share her inventions with her friends. They're big and bold and loud - just like her!

But there's one underwater creature who doesn't seem to enjoy Oona's company, or her creations.

And that's Stanley the shark!

Oona's latest hopping, chopping and popping inventions just make him angry.

Oona may not know what Stanley likes, but she does know what he doesn't. And maybe that's a good place to start. Because mermaids never stop trying . . . not when there's a friend out there to make.

From the New York Times bestselling author Kelly DiPucchio and featuring the extraordinary illustrative talents of Raissa Figueroa, the dynamic partnership behind Oona.
