The Baby-Sitters Club Vol. 4: Claudia and Mean Janine
Claudia and her sister Janine may as well be from two different planets. Claudia pays more attention to her art than her grades. Janine studies non-stop to get straight As. The girls are nothing alike, and they can't agree on anything. But when something terrible happens to their grandmother Mimi, the two sisters discover they're more alike than they originally thought!
