Greg Cox wrote four books that tie themselves together through the use of Khan and Gary Seven. They are all tied to the larger novelverse through the use of the flag for Khan established in the novel Section 31: Abyss, a part of the post-finale DS9 series. (Although the depiction of the Tal Shiar in Assignment Eternity differs somewhat from the depiction in the "Vulcan's Noun" series.)
Cox referenced "The Aliens Are Coming" by Dayton Ward from Strange New Worlds III in The Eugenics Wars.
- Assignment Eternity
- The Eugenics Wars: The Rise and Fall of Khan Noonian Singh, Volume 1
- The Eugenics Wars: The Rise and Fall of Khan Noonian Singh, Volume 2
- To Reign in Hell: The Exile of Khan Noonian Singh
^Depends on how you look at it.
Endgame (the Voyager finale) is what "pissed off" the Borg
The TNG Novel Resistance is where they first start to appear and cause problems after that.
The TNG Novel Before Dishonor is where the first really big thing occurs.
The Destiny Trilogy is the whole big event -- and likely is the more direct answer to your actual question.![]()

The TNG Novel Before Dishonor is where the first really big thing occurs.
I'd also recommend Q & A between Resistance and Before Dishonor. While it is disconnected from the Borg story it does introduce one recurring and one new regular (or recurring we don't know how long the character will be around yet) character. It's also a really fun Q adventure that ties most of his appearances together into one big story.
Which story in The Brave in the Bold referenced which story in The Badlands?
