On Monday It seems that only Claudia is aware that Charles is gone. Monday and Claudia have never been apart; they are more like sisters than pals. Claudia is concerned when Monday fails to show up for the first day of classes. Claudia becomes suspicious when she fails to show up for the second day or week. She wouldn't have to face exams and bullies by herself on Monday. Not with her grades on the line, not after the rumours from the previous year. More than ever, Claudia needs her closest friend—and only friend. However, Monday's sister April is even less helpful, and Monday's mother won't give Claudia a straight answer.
When Claudia looks into her friend's disappearance further, she finds that no one appears to know when they last saw Monday. How is it possible for a teenage girl to just disappear and no one to notice?
