Chagrined and astounded that unconventional Aunt Mattie is his fifth-grade substitute teacher for the remainder of the year, Simon, from No More Nice (1996), steadily develops as a character. His classmates are determined to maintain their power and reputation for pushing teachers to the limit, but Aunt Mattie profoundly changes their perspective and goals. Though the continuation from the first is smoothly done, this stands alone well. MacDonald uses a timely theme for children who typically feel unbalanced, at this age, by the realization that they are embarrassed in public by things that they are comfortable with at home. Though the message is slightly strong, it is not belabored: regardless of the apparent humiliation, children need to handle their fear of being ridiculed and confidently develop their beliefs. The plot captures immediate interest, which holds up throughout. Line drawings echo the light humor and reflect the text rather than providing additional insight. The humor is enhanced by the silly stereotyped characterizations of the one-dimensional, power-hungry vice principal and the unprincipled rival teacher. Their inane cruelty blinds them to Aunt Mattie’s and the children’s potential. Their unnecessary wickedness pushes the plot to its conclusion. Slight glimpses into the depth of various characters are seen through Simon, whose major focus is upon himself and his classmates. Leaving room for a welcome third story, this is a fast read for children who want something funny and light. (Fiction. 8-10)
