I will start with the books I have been reading lately, which are some of the most recently published. I will eventually go back to review the older books, but wanted to start with what is fresh in my mind.
The things I value most in a Stargate novel (and as such will be reflected in my reviews) are interesting storyline and accurate characterization. I hate seeing my friends (characters) do or say something out of character, and there's little point in reading a book that isn't interesting. I give high marks for incorporating new ideas into familiar plots lines (such as finding out more about the Ancients while sticking to canon). I also happen to like to see Jack O'Neill and Sam Carter together, so I will mention it, but it's not a requirement.
