By Sara Pennypacker, Author & Marla Frazee, Illustrator. Clementine is NOT having a good week. On Monday she's sent to the principal's office for cutting off Margaret's hair. On Tuesday, Margaret's mother is mad at her. On Wednesday, she's sent to the principal, again. On Thursday, Margaret stops speaking to her. Then Friday starts with yucky eggs and only gets worse. And by Saturday, even her mother is mad at her. Okay, fine. Clementine is having a DISASTROUS week. But maybe can she find a way to make it better. For ages 6 and up.
