Personally I do not have much faith in library lending, hopefully some one else will be along that can help there. I believe that the Nook can handle epub formated books which means that you can get book 2 anywhere at all. I have done some looking around the information super highway and I am yet to find the book anywhere in an electronic format, you might have to buy it in dead wood format and read that

What may be happending is that the publisher, TOR books may have neglected to produce the electronic format version of book 2, this happends sometime.
I read the book many years ago and let me tell you this book is better then book one, in my opinion. In this book you will read about a spelled temple where wizzards are trained and the women who work there. In the late part of the book you will read about the towers and the Emperor. I will say nothing more about the content since it will ruin the book.
