Cassie Bell is used to mess. Her cleaning business, Bluebell Cleaning, is well known in the Cumbrian village of Red Moss. However, now it's almost Christmas and Cassie has a slightly messier situation to deal with than she's used to. She's been hired to help Stefan Lambert, an injured army helicopter pilot who's staying at the local Belthorn Manor whilst he recovers. Stefan resents Cassie's interference and is definitely not looking for Christmas cheer. But Cassie prides herself on sparkling surfaces - can she bring some festive sparkle to Stefan's life too?
