I hated this book, and couldn't bring myself to read past the first couple chapters. The author describes various metaphors for programming in the beginning, comparing them to metaphors for science. I didn't think this added anything to the discussion. As I read the book I felt that the author was talking down to me rather than carrying on a conversation. I don't think this book is of any value, and would strongly suggest you check it out from a library before you buy it (I wish I had).
