When software engineer Keith Trainor decides to start his own company, he knows exactly who he wants as his partner: Parker Mulvaney, his best friend from high school. But in the ten years since graduation, their contact has dwindled to nothing, and it’s all Keith’s fault. If he hadn’t tried to kiss Parker under the mistletoe at the winter formal their senior year, Parker wouldn’t have bolted. At their ten-year reunion, Keith intends to do everything in his geeky power to make amends.

Parker should have known that scheduling the reunion the day before Christmas Eve was a recipe for a headache of monster proportions. But when Keith sends a text that he’ll be attending, the evening doesn’t look so bleak. Can an unnecessary makeover, a nostalgic breakfast, an abortive shopping trip, and a whole lot of mistletoe culminate in a long-overdue first kiss?
