Of course, I'm a co-author! We spent over a year writing it, and we just released it this past week. It's targeted at Java developers who are new to EJB or have worked with EJB 2.x. Lots of code samples, on-line examples using ant and Glassfish (Sun's reference implementation).
Raghu and I are going to be hosting a chat on the book and on EJB 3 in general later this month, and I hope you will join us.

If you are more interested in how to not screw up a J2EE project, then I highly recommend that you read:
There is certainly a lot of good stuff in Rod's book that still applies, but remember that it was written about EJB 2 before EJB 3.0 came out. Rod has since written the foreword for our book Pro EJB 3: Java Persistence API and strongly endorses EJB 3.0 JPA.
