The title fits the book perfectly. This is basically the very honest narrative of a character (Bob) whose life didn't quite turn out the way he wanted. In the process of exploring his past, there doesn't seem to be a single "fork in the road" moment to trace back where everything went bad. Instead, as is so much more common, he sees innumerable minute compromises... no individual one a keystone to the life he has lived, but each one an incremental step towards the place where he now finds himself. There are plenty of works of great fiction which still "feel" like fiction, but this is fiction which feels real- this could really be an interview with an actual person (if anybody is so introspective, honest, and insightful as Bob), which is testiment to the Joseph Heller's craft and honesty.
