I'd put in another vote for Kristen Beyer's Relaunch series, which starts with Full Circle.
If you're looking for TV series era stuff, I've only read a handful, but I'd recommend all of them.
The String Theory trilogy is really good, the first one is the best, but the whole trilogy is worth a read.
I recently read the Gateways Voyager book, No Man's Land, and the concluding novella, In the Queue, and enjoyed them.
If you want some different takes on the series, there have also been Myriad Universes and Mirror Universe stories featuring the Voyager cast.
The first Myriad Universes book, Infinity's Prism, features
@Christopher L. Bennett's novella, Place of Exile. It takes place in an alternate universe in which Janeway does not make an alliance with the Borg during the events of Scorpion, and takes things in a very different direction from where the show went after that.
The Mirror Universe versions of the characters first appear in The Mirror Scaled Serpent,
@KRAD (Keith R.A. DeCandido)'s novella in Obsidian Alliances. In this one instead of crew of Voyager going to the Delta Quadrant, Kes and Neelix end up in the Alpha Quadrant, and get picked up by a Rebel ship commanded by Chakotay with most of the Voyager crew on board.
