I obviously cannot read this morning, sorry about that! There's "The Best of Trek #4" but that's not an official book from my understanding.
Not even close to official. Have managed to glom onto a complete set. The articles veer wildly from being very insightful to horrifying levels of cringeworthy. An interesting look back a pre-internet fandom in any case.
Are you looking for books that specifically tie into elements from The Motion Picture or just stuff in that era? I'm not sure how many of them tie directly back to TMP, but there quite a few books and comics set in that era.
The crew members (from TMP) that Christopher L Bennett developed for "Ex Machina" have continued in his other books, "Mere Anarchy: The Darkness Drops Again" and "Department of Temporal Investigations: Forgotten History" and the forthcoming "The Higher Frontier". Comic-wise, Glenn Greenberg wrote a post-TMP mini-series for Marvel/Paramount: https://www.startrekcomics.info/marvel2untold.html It is believed that Leviathan, another massive sentient machine, was related to V'ger and possibly from the same machine planet. (Marvel/Paramount "Voyager" comic, "Leviathan".) The IDW mini-series "Nero" featured the Kelvinverse iteration of V'ger. Also from IDW, there was a "Waypoint" comic story featuring Xon ("Phase II"), and another with the merged V'ger/Decker and Ilia meeting Q.
The eBook novella Shadow of the Machine does an alternate take on the post-TMP setting. The TNG / TLE novel The Buried Age has a cameo by V'Ger.
As Therin mentions above, the first issue of Marvel's Untold Voyages mini-series shows the Enterprise searching the former location of the Epsilon IX monitoring-station for survivors immediately after the final scene of TMP, and the DC graphic novel Debt of Honor features a section likewise set shortly after the film's ending (and therefore prior to Christopher's novel Ex Machina) depicting the Enterprise retracing the course of V'Ger's journey.
Actually I believe "Shadow of the Machine" is supposed to take place in the same continuity as "Ex Machina" (I think at least that was the author's intent. Christopher had mentioned in another thread that he returned the favor by mentioning something about "Shadow..." in his upcoming post-TMP novel.
No, that was the other post-TMP e-novella, Scott Pearson's The More Things Change. That book acknowledged my Ex Machina continuity and thus I returned the favor. Shadow of the Machine is an alternate take on the events after TMP, incompatible with Ex Machina.
Oops. My bad. I read both stories but got my titles backwards This is why I usually check Memory Alpha for these things. The one time I get lazy....sigh
But....I know this thread is about V'Ger specifically, but I'd still highly recommend Ex Machina. It does deal with the aftermath of the V'Ger encounter and is an excellent post-TMP novel in its own right. It might not be a book about V'Ger per se, but it picks up basically where TMP left off. If you liked TMP I think you'll like Ex Machina
I'd say Ex Machina is the closest thing there is in Trek lit to a book about V'Ger, because it deals with the impact of V'Ger's advent, and the villain's actions are catalyzed by the events of TMP. Although my upcoming The Higher Frontier touches on further aftereffects of the V'Ger incident, to an extent.
I read it a few years ago. I liked the characterizations and I liked how Ensign what’s his name was expanded on. But my expectations were that it would be more closely related to VGer than For the World is Hollow. I should give it a second read. I enjoyed it.
