Chloe has spent four years at Willowgrove Christian Academy in small-town Alabama working toward one goal: becoming valedictorian. She moved from California with her two moms and has mostly kept her head down, avoiding gossip and navigating the conservative school environment. Her only real competition is Shara Wheeler—the charming, perfect prom queen who happens to be the principal’s daughter. A month before graduation, Shara shocks Chloe by kissing her in an elevator, then vanishes without explanation. Furious and confused, Chloe launches a desperate search for answers. She discovers she’s not the only one Shara kissed—there’s also Smith, Shara’s longtime quarterback boyfriend, and Rory, her bad-boy neighbor with an unrequited crush. The three unlikely allies discover Shara has left behind a trail of cryptic pink stationery clues for them to follow.
