Nolan Callahan, ghost of Christmas past, intends to spend this holiday haunting like every other--get in, get out, return to his otherwise aimless existence as a ghost awaiting the afterlife. But when he's faced with Harriet York, the sweetest assignment he's ever had, he suddenly finds himself wishing for a future. Harriet York has no idea why she's being haunted. She's a good person or, at least, she tries to be. A people pleaser to her core, she always does what's expected of her. But as she and Nolan begin to examine her past, they discover there are threads that bind them together and realize there might be more to moving on than expected. With the deadline of Christmas Eve fast approaching, will they find the key to their futures in each other's pasts? Or will they stay firmly in the present, indulging in their unexpected, spirited connection?
