Also, the book is poorly organized. Instead of having a more in depth table of contents, the authors just refer to other parts of the book as you read along, making it a little awkward if you try to flip back and forth. And though they do mention some other good books to read on different subjects, they could have complied them in the back of the book for easier reference.
So all in all, if you just want to do some light reading, a pick up a few pointers and learn a few random facts, (like what states "shacking up" is illegal in) go on and read it. At the library.
