When quiet, bookish Izzy Simon accepts a two-week assignment as an assistant for an author of children's books, it seems like the perfect way for her to make some much-needed extra money, but the grumpy author claims he doesn't want or need her services. He might be as handsome as a storybook prince, but his prickly personality and resistance to all things Christmas are sure to make for a chilly holiday season.
Derek Croft never agreed to the cheery temp his staff arranges for him while they're on vacation. Izzy is his polar opposite, but Derek soon realizes she could be the perfect solution to his interfering family...if he can get her to agree to pretend to be his live-in girlfriend. Before long Izzy's sweet disposition and unflappable optimism has him decorating a tree and looking forward to late night hot cocoa, but he's all too aware their time together can't last.
