Chloe Green has spent four years at Willowgrove Christian Academy in False Beach, Alabama, focused on one goal: beating prom queen Shara Wheeler for valedictorian. Just before graduation, Shara unexpectedly kisses Chloe and then vanishes, leaving behind a trail of cryptic notes. Determined to find her rival and claim her academic victory, Chloe embarks on a scavenger hunt.
Chloe soon discovers she is not the only one Shara kissed before disappearing. Shara also left clues for her longtime boyfriend, Smith, and her bad-boy neighbor, Rory. The unlikely trio, with nothing in common but their connection to Shara, must work together to decipher the messages. As they follow Shara's intricate puzzle through their small, conservative town, Chloe begins to question her assumptions about Shara, their school, and even herself. This journey forces Chloe to confront hidden truths and reconsider what it means to truly know someone, and what she is willing to risk for self-discovery and love.
