Dragonspell... Donita K. Paul

I looked up the books by the author who was at Nemo's Saturday. Her name is Donita Paul and her books are:
Dragonspell
Dragonquest
Dragonknight
Dragonfire
and a 5th book being published in June 2008.
I took a look at the book covers at Barnes & Noble and we own a couple of these. I have not read them, but Josh has. The reviews at BN indicated that they are a good read for both kids and for adults. I plan to read them soon...
