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, and 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 community and its children. 304 pp. 100,000 print.
