It's Christmas-time in New York, and world-weary Dash has managed to persuade each of his parents that he is staying with the other, thus sending them both off with their new 'paramours' and leaving him happily shuffling back and forth between their empty apartments. Meanwhile, Christmas-loving Lily is bereft at the thought of spending Christmas without her full complement of family, and has been consoling herself with cookie-baking and carols-singing. When Lily's brother plants a red moleskin notebook in Dash's favourite store, leaving instructions that lead him not only around the bookstore but eventually out into the Christmas-sozzled city, the scene is set for a back-and-forth series of clues, coincidences and missed rendezvous. Will sarcastic, intriguing Dash finally meet up with nerdy but loveable Lily? Only time will tell as the two teenagers try to outwit each other for as long as possible in this charming twist on the classic game of cat and mouse.
