Claudia and Mean Janine

Claudia is the resident artist of the Baby-sitters Club, and she is tired of living in the shadow of her older sister Janine. Janine is a genius, praised for her straight A's, her computer skills and her extra classes. Claudia struggles in every subject except art.

The two sisters barely get along. The one person at home who always seems to take Claudia's side is their grandmother, Mimi.

Then Mimi has a stroke, and life in the house shifts. Claudia helps look after her grandmother, and the hours she can give the club shrink. She and Janine have to cooperate to give Mimi the care she needs.

That forced teamwork slowly changes how each girl sees the other. Raina Telgemeier adapts Ann M. Martin's novel from 1987 into comics form, as the fourth volume of the Baby-Sitters Club graphic novels. A black and white edition appeared in 2008, followed in 2016 by a full-color edition with color by Braden Lamb.

The question driving it is whether two sisters who can barely share a room can share the care of someone they both love.
