^ Typhon Pact
had initially been conceived as a six-book series, but at some point, that got scaled back to four volumes. David Mack's Zero Sum Game
features the Breen; Michael A. Martin's Seize the Fire
involves the Gorn; my Rough Beasts of Empire
covers the Romulans and, to a lesser extent, the Tzenkethi; and finally Dayton Ward's Paths of Disharmony
deals with the Tholians. I don't believe that the Kinshaya appear.
As for Rough Beasts
, I'll reiterate that it is not truly a Deep Space Nine
novel. Ben Sisko features prominently in it, though. The other main character is Spock.
