This book is pretty basic. It's not a bad start if you're coming from CVS or SVN with zero DVCS experience (git, bzr, hg, bk, ...). A book on Git should either be for the user who wants to maintain their CVS/SVN workflow but with Git or it should be for the whacked out uber coder who wants to get crazy wid it (like moi). Sadly, this book tries to be both without really being either. If you're interested in reading it, see if you can bum it off a friend.
