The further adventures of the Quimby family as Ramona enters the third grade.

Ramona meets lots of interesting people in kindergarten class, like Davy whom she keeps trying to kiss and Susan whose springy curls seem to ask to be pulled.

Ramona's year in third grade is highlighted by the arrival of Howie's rich uncle, a change in her afterschool situation, a surprise wedding, a death and a new arrival in the family, and her father's getting a job.

Ramona at 7 1/2 sometimes feels discriminated against by being the youngest in the family.
