Boring, dry, humourless, etc., are all words that can be used to describe this book.

As for it being an "introduction", I am not sure I agree. In my opinion, you need to have some cursory knowledge about the subject (ITIL) to be able to read it at all!

That said, it is an excellent summary-like book on ITIL, when you want to have just the bare facts presented in an efficient manner.

In short, this is for the already converted, but for them, it is a decent book.
