The "Borg Invasion" series is Star Trek: Destiny.
https://www.amazon.com/Destiny-Compl.../dp/B00AHE24ZS
Basically it is the sequel to the last Episode of Voyager. It takes place in 2381 (18 months after Star Trek: Nemesis) and is pretty much "the big one"... the massive Borg offensive against the Alpha Quadrant and the Federation. It takes place also after the first bit of Star Trek: Titan (Riker post Nemesis), the DS9 relaunch and Voyager relaunch, so there is some things like Ezri Dax being a captain of the most advanced ship in Starfleet.
The best way to think of Star Trek Destiny is as the "all-24th century" event movie that never happened but really should have. The one that would have brought TNG, Voyager and DS9 together after Nemesis. It's the biggest story Star Trek ever had. Yes, even bigger than the Dominion War. Its the summation of almost everything since "Q Who?" in TNG Season 2, and that includes Star Trek: Enterprise (the NX-02 Columbia plays a big role).
Destiny is also the point at which Star Trek novels started to gain consistency series to series, author to author, rather than have a lot of contradictions between them.
It's followed up by "Star Trek: Typhon Pact" which takes place after Destiny.

Pretty much the post-Borg invasion Alpha Quadrant is a mess, and two powers coalsese in open political and military competition: the Khitomer Alliance (Federation, Klingons, Ferengi, half of the Romulans and others), and the Typhon Pact (other half of the Romulans, Gorn, Breen, Tholians). It is a kind of situation like NATO and the Warsaw Pact after World War II. Interesting things happen. A lot of status-quos change with major characters, especially with DS9.
It's followed by Cold Equations

There are a big number of one off books after that, but most relevant is the Section 31 books, which brings us to "Control":

One of the important things to note about the book series is that time has slowed down some compared to the real world. In the TV show, 1 season of the show roughly corresponded to 1 year in fictional universe, so by the end of TNG, the Enterprise D crew had been at it for 7 years, end of DS9 that crew for 7 years and so forth. With th ebooks, the latest ones are in 2386, which places it just 6.5 years after Star Trek Nemesis.
Why is this important? Because the books are coming up against their long avoided "upper bound", which is the destruction of Romulus in the Prime Reality part of JJ Abrams' Star Trek movie. That takes place in 2387, and is a major paradigm shift in the Prime Universe (as evidenced by it being a central plot point of the new Picard show), but just by the nature of what's gone on in the novel series, the entire status quo of them would have to change because of that (the fallout of Shinzon of Remus' brief takeover of the Romulan Star Empire in Nemesis is as major plot point for many books).
Star Trek novels used to be terrible, but since Destiny, they've gotten really pretty good and unlike a lot of books based on licensed properties (Star Wars), isn't afraid to majorly change characters. It does do a bit much of of "everything is connected" but they've really gone places in them.

Oh and for what it's worth, at the top of that list is a whole list of Star Trek: Enterprise books that are also pretty good, that take place just before and during the Romulan War, then the founding of the Federation.

My starting point for this has been the post-war prophecy of Section 31 in Inter Arma Enim Silent Leges. That in the decades after the Dominion War, with the Klingon Empire vastly weakened by it (and it's own war with Cardassia, and the Federation during DS9), the main Alpha/Beta quadrant rivals were the Romulan Star Empire and the Federation. That is, until, the Hobus star destroyed Romulus, and the Romulan Empire fell into warlordism.
And what happened then? Over the next 15 years (though not immediately) the Klingon Empire, which went somewhat isolationist to recover after the war, decided to claim as much of the Romulan Empire remnant as it could, and their post-Martok chancellor emphasizing a back to basics approach leads a revionist Empire into a new war with the Federation.
In my view, if you cut out the (then) unnecessary stuff with Burnham and Sarek and little else, Star Trek Discovery season 1 could have been the show exploring that, but in like 2420. You know "50 years later, the Klingon Empire came back". Almost every complaint about continuity breaking could have been resolved by making it a "50 years after the Dominion War" show. It would have meant shedding the Spock connection, and is clearly impossible to fit Season 2 in with that vision, but I think it would have probably made for a better show.
