I have been busy trying to catch up with a big pile of books on my nightstand and finished Working with NHibernate 3.0. I must admit that I was left with somewhat mixed feelings after finishing the book. There are lot of examples and author does good work showing different ways of accomplishing same result. At the same time, the book is rather short (only a bit over 200 pages) and leaves a feeling that some details had to be omitted in order to cover everything that was placed inside the book. I think the book works as an introduction to the subject, but anything more in-depth information has to be gathered from somewhere else.
