In the Voyager relaunch series, some of the crew stays together under Captain Chakotay. Janeway becomes an Admiral, Seven of Nine joins a Starfleet "think tank" regarding the Borg, the Doctor advocates for "Holographic rights", and quite a few other things.
I believe these events are covered in the Christie Golden books:
Homecoming
Farther Shore
Spirit Walk
There might be more books in the series, but the above 3 I have read and they are quite good. Well worth the read.
