I have HIA, which is an excellent book. I highly recommend it. As noted above, though, the current version covers Hibernate 2. I've just ordered Pro Hibernate 3 (Apress), as that is the only book I can find that covers Hibernate 3 functionality. I've found other Apress books (particularly Pro Spring) to be good investments.
I'm certain that I will also pick up any updated version of HIA, if the authors write an update.
For what it's worth, I reviewed the Apress Pro Hibernate 3 on Amazon.com. It is a really small book (242 pages, including the index), so it doesn't go into the depth that I was looking for on more advanced/new features of Hibernate 3. For those looking for an introduction to Hibernate that absolutely need to learn Hibernate 3, this is the only option I know of out there. Personally, too much of the content was on stuff that existed in version 2 that I knew from the excellent HIA book. I sent my copy back. Which isn't to say it's a bad book; it's just not as good as HIA, and the exclusive Hibernate 3 content doesn't make up for that.
