Claudia and her sister, Janine, may as well be from two different planets. Claudia, who pays more attention to her art than her grades, feels she can't compete with her perfect sister. Janine studies nonstop, makes straight As, and even takes college-level courses. The girls are nothing alike, and they can't agree on anything. While Janine devotes all her time to working on her Web site, The Baby-sitters Club is busy with their new summer play group. But when something terrible happens to their grandmother, Mimi, the two sisters discover they're more alike than they originally thought.
