A new book that I wrote a couple of chapters for has just been released. It is Professional SQL Server 2012 Internals and Troubleshooting from Wrox. I really believe this is a high quality book from a collection of great authors (who somehow let me on the project) that I think people will enjoy.
There is a book signing at the SQLSentry booth in the Expo Hall at the PASS Summit 2012 today (November 8) at 12:30PM. SQLSentry is giving away a decent number of books through a raffle, so it is probably worth your while to show up and take your chances on getting a free copy. I hope to meet a lot of people in the Expo Hall today!
