Gina has always counted on Sissy. Sissy is loud, fearless, and funny in all the ways Gina isn’t, and she’s family to Sherry, the quieter cousin who never quite says what she’s really thinking. When a secret about a crush slips into the wrong hands, the balance between the three girls tilts in a way none of them are ready for.

Across restless school days and a long, complicated summer, Gina has to figure out what happens when your closest friend is also loyal to someone who suddenly feels like your enemy. Caught between hurt feelings, risky jokes that go too far, and moments of unexpected closeness, she starts to learn what real friendship looks like, and what it takes to hold on to it.
