Stacey's parents have been fighting a lot lately. Even so, she's still not prepared for the terrible news: her parents are getting divorced. Not only is Stacey sad and angry, but now she has a big decision to make: Stacey must either stay in New York with her father or move out with her mother ... to Stoneybrook. Could Stacey really leave the city, her father, her best friend Laine, and all that great shopping? But then again, how could Stacey pass up going back to her old school, all the kids in Stoneybrook ... and the members of the Baby-sitters Club?
