When Kyle Chase was eighteen, he had his life all mapped out: a business degree and a long, happy life with his childhood sweetheart. Seven years later, Kyle is still haunted by the girl who declared her everlasting love to him before disappearing without a word as soon as he left for college. With the realization that the memories are stopping him from living his life, Kyle posts an ad in hopes of making contact with the woman who broke his heart.

Sadie Long has finally found her niche in the world as an artist, years after leaving the South and her trailer-trash parents. Every month, her muse drives Sadie to create another artwork featuring a vivid full moon and the boy she left behind, and it's driving her crazy. When she comes across an ad in Craigslist’s “Missed Connections,” she knows it’s from him, and even though she’s terrified of how he might feel about what she did when they were teenagers, she has no choice but to respond to the ad.

When the truth comes out, will Kyle be able to forgive Sadie and move forward, or will they always be stuck in the past?
