This is a book from one of the Xp guru’s. Who am I to say, “I would not buy it”. Still I dare to say it. Not that it is a bad book, but reading one or two articles is probably enough. I would invest in a book like Agile Software Development with SCRUM to learn about planning a project. And I guess you should read : Extreme Programming Explained : Embrace Change (2nd Edition) to learn about extreme programming.

Conclusion, this could have been said in about 10 pages as well. I you haven’t read anything about xp this book might be interesting, but the two alternatives are better to my opinion.
