Rank this book if you've read it (Score 1)

I created this site about 6 months ago for programmers to rank their favorite programming books. The concept is simple, you rank your top 5 favorite books for a particular subject like "Ruby" or "Software Engineering". Specifically here are the top ranked Ruby Books. And here's the list of Top books every programmer should read. Of course, this only really works well if more people rank books, so if you've read this book, rank it(and any other ones you've read).
