I too, found out about the series through the show.  I loved the series.  I thought it was well thought out, wonderfully acted and not too over or under on the special effects.  (Yes, the dragon was small, but it was obviously a shape-shifter and making itself bigger than Harriy's office would not have been a good way to insure it's survival.)  It was about the sixth episode that I saw that the series was based on a set of books.  I wanted to buy them, but it took me a while to take the time to get them.  When I did, it took three books stores to find them and naturally my third one was Boarders.  They were having a sale on Jim's books.  I bought the whole series during the course of two weeks.  Read them all too.  Plan to go to the book signing tomorrow.  Still enjoy the series and can't wait for the next season.  However, the books are amazing and I'm now working on getting the whole set in hardcover.
