I absolutely LOVED 'Roswell'. It was the first SG novel I read and it was wonderful. I've read it at least twice if not three times...matter-a-fact...I've been looking for a satisfying hit of SG team-goodness...maybe I'll go read it again...yes I can just see all the raised eyebrows and groans from my family.
I found a couple of places where I questionned the author's choice of words for Daniel but it was very minor.

My absolutely favourite line was from Daniel:
"Duck Dodgers?"...
That entire scene with he and Jack had me literally laughing laugh out loud.
I also loved the hint of DV inherent in the scene near the end when Cam is talking about Vala being taken by Qetesh again.
All in all, an extremely satisfying read. Would make a fun movie.
I'd love to be able to write something similar for Fandemonium.
