In `the stifling heat of equatorial Newark`, a terrifying epidemic is raging, threatening the children of the New Jersey city with maiming, paralysis, life-long disability, even death. This is the startling and surprising theme of Roth`s wrenching new book: a wartime polio epidemic in the summer of 1944 and the effect it has on a closely-knit, family-oriented Newark community and its children. At the centre of Nemesis is a vigorous, dutiful, twenty-three-year old playground director, Bucky Cantor, a javelin thrower and a weightlifter, who is devoted to his charges and disappointed with himself because his weak eyes have excluded him from serving in the war alongside his contemporaries. Focusing on Cantor`s dilemmas as polio begins to ravage his playground - and on the everyday realities he faces - Roth leads us through every inch of emotion such a pestilence can breed: the fear, the panic, the anger, the bewilderment, the suffering, and the pain. Moving between the smouldering, malodorous streets of besieged Newark and Indian Hill, a pristine children`s summer camp high in the Poconos - whose `mountain air was purified of all contaminants` - Roth depicts a decent, energetic man with the best intentions struggling in his own private war against the epidemic. Roth is tenderly exact at every point about Cantor`s passage into personal disaster and no less exact about the condition of childhood. Through this story runs the dark question that haunts all four of Roth`s late short novels, Everyman, Indignation, The Humbling, and now, Nemesis: what choices fatally shape a life? How powerless is each of us up against the force of circumstances?
