This book is a criticism of religion. Specifically, it criticizes the inherently stupid things being done by humans in the name of the particular branch of religion that they happen to have been brought up with (like opposing abortion, stem-cell research, and embracing the idea of martyrdom). It's written as an open letter to a Christian, so it didn't particularly speak to me, but I imagine a Christian might have a mind-opening experience if he read it.
