I've said it many times and will probably say it again: The DS9 Relaunch is the best conceived and best executed series of novels I've ever seen. On top of that, I had my doubts that DS9 could enjoyably translate from one medium (TV) to another (novels).
I heartily recommend the entire run of books to anyone who loves Deep Space 9. I've introduced the two-part Avatar to other folks with the provision that if the person didn't like it, he or she could tell me I'm an idiot. So far, I've had no takers on the "idiot' thing, but I have been thanked for introducing them to the series.
And that's the truth.
