Here it is, it's now official! I'm currently writing a Maven book for O'Reilly with Tim O'Brien. I can't say much more at this point in time except that it'll be available sometime this summer.

I've also written 2 Maven quizzes for JavaBlackBelt.com. If you want to see if your Maven knowledge is up to the par, go and take them! And let me know your comments. If you register on the site you can even propose new questions!
