It all starts with a forgotten mailbox in the woods. A note slipped inside. And a reply from someone who should not exist.
Lila is certain there must be a logical explanation-until the letters keep coming, and Ethan, the stranger writing back, reveals a truth she cannot explain: he is living one day ahead of her. What follows is a connection neither of them expected and a mystery neither of them can ignore.
As the letters lead them closer to answers, they also pull them towards secrets that have been waiting far longer than either of them knows.
