Mr. Quimby's going to college, Mrs. Quimby's going to work. Now that Ramona is eight, she can go to a new school with a new teacher and ride the bus all by herself. But after school she has to stay with Grandmother Kemp and be nice to that bratty little Willa Jean until Beezus–who's temperamental enough to ruin anyone's day–comes to take her home. Life isn't as easy for Ramona as it used to be. All the Quimbys have to adjust, and Ramona gets her chance to prove that she's "big enough for her family to depend on."
