==Book Description==
"It usually takes me all week to read a book. With Mandie, I read about one book a day. I just can't put it down," writes a young reader from Michigan.
The school year is over and Mandie is coming home for the summer. Mandie Book readers will expect that she can hardly wait to be with her mother and stepfather, her friends and loved ones. But that's not the way it works out-
Ever since Mandie's mother told her she was going to have a baby, the thought of having to share her mother with a brother or sister has caused problems for her. When she arrives home these troubling thought become even stronger. And the baby never stops crying!
Mandie is about to take her future into her own hands. Can you guess what happens?
