Well, at the risk of engaging in shameless self-promotion, I might point you to my third book, which Oxford Univ. Press published last Monday. When Prayer Fails: Faith Healing, Children, and the Law examines the complex sociolegal issues raised when devoutly religious parents choose to treat their children with prayer rather than conventional medicine. It's pretty heavy stuff (there are lots of dying children, etc.), but it's written more for a general audience than for nerdy academics. (My first two books, also on law and religion, are pretty accessible as well.) If that doesn't float your boat, you might try Bruce Watson's new book on the Sacco and Vanzetti case. I've ready the first 50 pages, and it seems pretty engaging.
