One of our MVPs has written a book on VS 2012 ALM.  It’s not quite available yet and I haven’t had a chance to look at it closely, but Mathias has been working closely with us for a long time and I expect it will be a good book.  Here’s a link to where you can learn more and ultimately order it when it is available.
