I wouldn't even buy the new edition. The story itself is that bad and that inconsequential to the larger narrative. You can already infer Deception
's "plot revelations" from what happened in Retribution
Anyway, I'm continuing reading through the few Trek novels I've purchased and then never gotten around to reading/finishing. I just started Terok Nor: Day of the Vipers
. I bought it a couple of years ago, but at the time I'd yet to see all of DS9, and I don't think I was really in the right mood for it then, so I never finished it. Now that I've watched through all of DS9 (which I finally did last year, thank you Netflix!) I think I'll have a much easier time following the story and enjoying it.
