Alex is looking forward to spending the summer (as she’s always done) with her best friend, Will. Will’s mother runs the concession stand at their community pool, and both kids have spent several summers playing games at the pool. This summer, though, a schoolmate named Rebekah has eyes for Will — and him for her! As Rebekah and Will begin a tentative crush-friendship, Alex feels threatened and ropes Will into a big summer project (building their treehouse) for which they’ll need several summer jobs to afford building supplies. Surprisingly to Alex, Rebekah also wants to be her friend too. Can Alex get over her jealousy and other issues in her life to figure out this summer friendship drama?
