ISBN 0590423355 - Cute, and hardly a brain bender, Mom, You're Fired is a good title for the 9-12 age group (more 9 than 12). Every one of us will recognize ourselves in Tina and some of us will recognize ourselves in her mom.
Tina's mom is so embarrassing. She doesn't dress as nicely as Melissa's mother. And she sings - in public! Tina's lunches even embarrass her. So when she meets a new girl, she tells her that her mother is her babysitter and Tina begins a trail of lies she has to struggle to maintain. How it unravels is fairly predictable, but it's worthwhile.
Nice message without being too soap-box-ish. Robinson does an excellent job of telling a story with a moral without beating the reader about the head with it. This is the first book I've read by her, and I look forward to finding more.
