In Caterpillar Summer, Cat and her brother Chicken spend a lot of time together because no one knows how to calm him down like she does. Chicken hates loud noises and is obsessed with sharks. Since their father (who was Black) died, their mom (who is White) has had to work longer hours to provide for them. It doesn't help that she actually LOVES her job and is sometimes a bit too eager to leave Cat in charge of her brother.
In The Queen Bee and Me, Beatrix and Meg have always been a package deal -- best friends since kindergarten! Lately though, things have changed between the girls. Meg can't forget the time Beatrix froze her out when she annoyed her and she's also noticed that Beatrix can't stand it when she disagrees with any of her opinions. Still, Meg loves science and when she's invited to join a special advanced science class, she can't say no.
