This book is a digest of the 25 most interesting quizzes and their solutions carefully collected by James and released in one volume (using some very pretty typesetting, I must add). It's basically a printed version of the website, with only very little content added - like additional exercises after each quiz. And this is where the problem of this book lays, in my opinion. To experienced programmers it won't be particularly interesting, since looking at the quiz website itself and participating in the lively discussion on the maling list is much more interesting. This book could be excellent for newbies, but unfortunately it's not meant for those unfamiliar with the language. So even here, the website is just far more useful. The only real advantage of this book is its dead-tree format, which may be nice for people who have difficulty reading from the computer screen, or for people temporarily without internet access.
