When gorgeous neurosurgeon Sheridan Rousseau walks into Lisette Mouton's charming little bookstore in Quebec City, she unknowingly holds the key to a mysterious box hidden in a secret room. Upon opening the box, they discover an ancient locket with a photo of Marie Antoinette, a vial of perfume, and an old map.

Attraction simmers between Lisette and Sheridan, helped along by their scheming assistants, and the clues they discover in the bookstore lead them on a hunt across Canada for buried treasure. Best third date ever. But as the weeks go by, the trail grows cold, and Sheridan wants to return to her waiting patients. Lisette has been walked away from before, and she isn't letting Sheridan give up the hunt-or, it seems, her too. Will the map to love prove to be the greatest mystery of all?
