To escape the holiday blues and the cold and monotony of winter, sixty-something widows and best friends, Wendy and Amie happily head south to attend the wedding of Wendy's environmentally conscious nephew. 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.
