The humid air of Willowgrove Christian Academy hangs thick with the scent of old money and even older rules. For Chloe Green, transplanted from sunny Southern California, this Alabama institution has been a four-year obstacle course of whispered judgments and the ever-watchful eye of the administration. Her sole focus has been the valedictorian crown, a prize she’s meticulously pursued, her only competition the seemingly flawless Shara Wheeler, daughter of the principal. Then, a month before commencement, Shara does the unthinkable: she kisses Chloe, and then disappears. Driven by a furious need for answers, Chloe discovers she’s not the only one Shara left behind. Smith, the golden quarterback, and Rory, the brooding neighbor, are also caught in Shara’s orbit, each bearing the mark of her kiss. Bound by a shared enigma and Shara’s cryptic, monogrammed notes, this unlikely trio must follow a trail of clues through clandestine parties and whispered secrets, uncovering more about their small town and the girl who vanished than they ever imagined. As they chase a phantom, piecing together a puzzle left on fancy stationery, Chloe begins to wonder if there’s more beneath the surface of Willowgrove, and perhaps, more to Shara herself than anyone knew.
