The first installment in a brand-new, original chapter-book series set in the world of Max's hit TV show Mermicorno: Starfall and written by New York Times bestselling author Kiki Thorpe

After their defeat at Ika's lair and their arrival at the Pearl Palace, Kameko is anxious to find her dad, who is missing at sea. But Royal Mother Pearl tells her that the ocean is simply too dangerous right now!

Kameko, who can't just sit and wait, starts writing messages in bottles and releasing them, hoping that one will find its way to her dad and help them reunite. Nautique knows that this task is futile. The ocean is huge, after all.

Kameko adores her Mermicorno friends. But as the only Mermaid-icorno in the group, she sometimes feels left out. Nautique and Squishella are besties, and Astra and Gwen clearly have a special connection. So who is Kameko's best friend?

As the Mermicornos make plans to find the Mermicorno Kingdom, Kameko starts to feel more than ever that she needs a best friend. Will a friend help her find her dad?
