The listing, Whatever Happened to Janie? has ended.
Paperback by Caroline B. Cooney. Fabulous book for kids and adults alike! I love this book, i'm clearing out all my duplicates.
The plot-
Janie has moved back to live with the Springs. She's supposed to go cold turkey, having no contact with her Connecticut family for three months. Her sister, Jodie, has especially looked forward to her return.
Although Janie promised to try her best to fit in, she feels enormous resentment at having to leave her upper-class, loving home to live in the crowded, middle-class loving home of strangers.
She calls her parents "Mr. and Mrs. Spring," and keeps referring to her "mother" and "father" in Connecticut. The Spring family try their best to help her adjust, but she insists on writing her Connecticut name on her homework and on calling her Connecticut family every day.
When her boyfriend, Reeve, arrives unannounced to visit, she relaxes. At last, Janie makes the decision to go home. Enraged, her sister and her brother, Steve, go to New York, attempting to find the woman who kidnapped Janie.
Happy bidding, and Good Luck!
