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!
