Frankie Thompson has her December all mapped out. Long shifts at the hospital and a trip to Boston to spend Christmas with her family. The only thing not on her list? The grumpy neighbor across the street who makes it clear he has no interest in holiday cheer. Sam Nicholas prefers his solitude. After walking away from a life that cost him more than it gave, he’s content to keep his distance from twinkling lights and seasonal fuss. Peace and quiet—that’s all he wants. But when a snowstorm knocks out the power and pushes Frankie into his orbit, his carefully guarded world begins to shift. Letting her in was supposed to be simple. Instead, the storm brings shared meals, late-night conversations, and sparks that make the walls around Sam’s heart begin to crack. Frankie knows she should be packing for Boston, not lingering in a house that feels more like home than she ever expected. And Sam knows better than to let himself believe in Christmas miracles. But the storm has other plans. Unexpected Christmas is a grumpy/sunshine holiday romance filled with cozy banter, reluctant neighbors, and the kind of love that sneaks up when you least expect it.
