Snow and murder follow the women, and Wendy is once more forced to put her puzzle-solving skills to work to identify the killer. Amie warns her that accusing someone of murder is not like a puzzle where a mistake can be simply erased. Further complicating matters, the possibility of romance threatens the friend's relationship.

Part travelogue combined with an old-fashion murder mystery, Sinister Snowbirds is the second in a series featuring the adventures of Wendy and Amie.
