The latest easy chapter book about Marvin starts off with the usual hilarious comedy. Marvin's teacher asks him to care for her aging dog, Waldo, while she's away for a week, and she gives Marvin the key to her house. First, there's the shock of seeing his teacher with a life outside the classroom (Mrs. North was almost like a real person). All his classmates envy him. He tries to act mature and responsible, not allowing his friends in Mrs. North's house, walking Waldo, coaxing Waldo to eat, even eating the dog food himself to make sure it's all right. But Waldo won't eat, and the story takes a surprising turn when the dog dies. Marvin must cope with his feelings of guilt and sadness and with his isolation as the kids at school and the substitute teacher turn on him. The farcical cover showing an embarrassed Marvin in his teacher's clothes closet is totally misleading. However, readers will relate to the tension and reversal in the story. They'll recognize Marvin's feelings, both the humor of having to confront your teacher as a person and the sorrow at the death of a beloved pet. (Reviewed June 1994)

When his third-grade teacher pays Marvin to take care of her old dog, Waldo, while she's away, his friends think Marvin is 'the luckiest kid in the whole world'--until Waldo dies. Sachar's finely tuned sense of how children think and feel make this fourth book about Marvin and his comic misadventures entertaining. Black-and-white drawings illustrate the story.
