Hannah Swan is looking forward to Christmas for the first time in years. Her new job as an eco-consultant is taking her - and her geeky colleague, Noah - to the beautiful Cornish village of Porthgolow for the first time. They're are helping the Crystal Waters Hotel to ramp up its green credentials, though after a bumpy journey, Hannah can't shake off the feeling that Porthgolow is strangely familiar. Never able to resist a mystery, her interest is piqued when the hotel's staff and customers report odd noises and sightings, believing the hotel to be haunted. When bad weather cuts off Porthgolow, Hannah and Noah are looking at a Cornish Christmas.
