Am currently on David Mack's Warpath. I think what follows are Fearful Symmetry & Soul Key and then I'm caught up on the pre-Destiny DS9 novels. Is that right? Nothing after Soul Key in DS9 novels prior to the big changes in Destiny?
Essentially correct, although "Reservoir Ferengi" in the Seven Deadly Sins anthology does fill in the year after The Soul Key as far as Brunt, Gaila, and some other DS9 side characters are concerned.
