An Alaskan cruise is the setting for amateur detective Sadie Hoffmiller’s latest adventure. Sadie plans to spend time relaxing with her two grown children, Breanna and Shawn, and her boyfriend, Pete, while enjoying the luxury and cuisine of an elegant cruise ship and helping to plan her daughters upcoming wedding. But even as the crew prepares to leave port, Sadie has suspicions about the voyage ahead and the relationship between her normally easy-going son and a mysterious female passenger he obviously knows but refuses to discuss.
When the woman is discovered unconscious during the second night at sea, Sadie’s apprehension escalates. Over the last few years, Sadie has developed an extreme dislike for secrets and it would seem her son is keeping one from her.
