Eleven-year-old Anthoni Gillis is not the kind of kid who believes in fairies, unicorns, or even the word "maybe". She's more of a comic-book girl. So when her mom brings her to Thunder Lake for a summer at the Showboat Resort, she doesn't believe the local rumors about the Boulay Mermaid. Anthoni has bigger fish to fry. She's always wanted a True Blue Friend. But it's been hard to find one, since for the past five years she's been bouncing from town to town, helping her mother sell Beauty & the Bee cosmetic products to keep them both afloat. This summer will be different, though. Anthoni has a plan - a foolproof checklist for making lieflong friends! There won't be any maybes this time. But as she grows entangled in local gossip, and as her mother stretches the truth, Anthoni must decide if she'll "stick to the plan," like always, or dive into a summer full of extraordinary possibilities.
