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?
The book starts with Stacey McGill living in New York while she is babysitting the Walkers, her favorite charges, in the city.
Later when she returns to the family apartment she hears her parents fighting about money, lately they have been fighting a lot about her mom's shopping and her dad being a workoholic and rarely ever being home to see the family.
Crying she runs to Laine's apartment, and tells her about the fight between her parents thinking they are no longer in love with one another.
Later that night she finds out that her parents are getting a divorce, which makes her sad, and furious at them for divorcing.
A couple of weeks later, her mom decides to go back to Stoneybrook. Stacey goes back to Stoneybrook with her mom, rather than staying in New York with her dad.
In Welcome Back, Stacey, Stacey has been away from Stoneybrook since book #13. During the time that she was away, I realized that she was a crucial member of the Baby-sitters Club, and I wanted to return her to Stoneybrook. Also during that time, I was beginning to receive more and more letters. Many of them were from readers whose parents were going through a divorce, just like Stacey’s. Some of them, like Stacey, were faced with difficult decisions. They said that they felt confused, and wished they could read a story about a favorite character who is in their position. And that was how the idea for Welcome Back, Stacey was born.
