On the subject of dragons, I have stumbled upon a book called Dragonspell by Donita K. Paul. I found it at Barnes and Noble while looking at Terry Pratchett books. It is the first book in a five-book series. The books are Dragonspell, Dragonquest, Dragonknight, Dragonfire, and Dragonlight. I highly recommend the series for dragon-lovers.
Side-note: If you go to Borders, they are filed under Christian Fiction. I see no reason as to why it can't be under Sci-Fi/Fantasy, but that is Borders problem.
