Suppose that an unusually large number of children in your town developed cancers that seemed to result from an environmental hazard such as air or water pollution. What would it take to prove it? A group of parents in Toms River, NJ, found out when their children were diagnosed with cancers that they believed to have been caused by toxic wastes dumped by the town’s largest employer. Dan Fagin describes their fight for justice in Toms River: A Story of Science and Salvation (Bantam, 2013), an environmental detective story that involves midnight dumping, criminal sabotage, and other subterfuge. A review of the book will appear soon on One-Minute Book Reviews.
