Roth continues his string of small, antiHoratio Alger novels (The Humbling; etc.) with this underwhelming account of Bucky Cantor, the young playground director of the Chancellor Avenue playground in 1944 Newark. When a polio outbreak ravages the ki ds at the playground, Bucky, a hero to the boys, becomes spooked and gives in to the wishes of his fiancée, who wants him to take a job at the Pocono summer camp where she works. But this being a Roth novel, Bucky can't hide from his fate. Fast-forwa rd to 1971, when Arnie Mesnikoff, the subtle narrator and one of the boys from Chancellor, runs into Bucky, now a shambles, and hears the rest of his story of piercing if needless guilt, bad luck, and poor decisions. Unfortunately, Bucky's too simple a character to drive the novel, and the traits that make him a good playground director--not very bright, quite polite, beloved, straight thinking--make him a lackluster protagonist. For Roth, it's surprisingly timid.
