Not only describes XP very well, but also explains why it works. It is full of practical and useful insights (even more so than 'The Mythical Man Month') - it's obviously the result of real experience rather than being theoretical. It deserves to become a sw development classic.
It's easy to read - much more so than the XP wiki sites - which by their nature are rather 'bitty'. Although the wiki sites contain more detailed discussions about the practices, the book explains why the practices work together.
