Query: Houston, we have a problem...

I don't know if every copy of the book is like this, but mine was printed so faintly that the highlighting of the examples was too faint to see. What this means is that the examples in the book (and there are a lot of them... that is the primary method of teaching in the book) are useless without the accompanying text. The accompanying text is quite good and thorough, but I wouldn't recommend this book at all unless you're sure they've fixed the problem at the printer.
