As a favor to her brother, Marnie McLaughlan has agreed to spend Christmas at the lovely Mirabel Inn—as a mystery guest. But Marnie knows this favor is bound to be complicated because the owners need a confidential report immediately. Marnie's impressions could affect their decision to sell. From the outset, the inn is not what she expects…and neither is the manager, Luke Harrison. She quickly develops a rapport with this very attractive widower and his adorable little boy. He knows something is up, yet she can't tell him that the inn—which is home to Luke and his son—is in danger. Marnie's torn between her obligation to her brother and her growing love for Luke. Fortunately, things have a way of working out at Christmas!
