I purchased this book a number of years ago when I first began studying on the Jewish roots of the Christian faith. The book itself is hardbacked and has certainly withstood my opening closing, weighing down flat and all manner of rough handling. So far it is completely intact.
The contents of the book are extremely thorough and it is somewhat different from some of his other 'popular' works as the overall feel is more academic, whereas some of his others are more accessible. This is not a put down but in my mind reflects the intended audience be they other scholars, students of new testament or those with an avid interest in the subject. That said though, I would recommend it for anyone, after all, no one forces people to read the extensive footnotes or references contained within it.
Contentwise, the book does an excellent job of explaining the background, purpose (in the singular) and meaning of many new testament parables giving extensive parrallel similarities from Jewish literature pre and post.
