Michael Jan Friedman has written some great books. He's also written one of the worst Trek books ever written (Death in Winter). So it's a bit of a roll of the dice.
Honesstly, to get an idea of modern trek books, the Destiny trilogy gives a pretty perfect introduction and summary of the whole "litverse". And, like, in terms of a trek movie adventure, it's not the worst way to spend a few hours. But the style is very much nu-trek and it's not for me.
If you're a DS9 fan, the Avatar (1&2) books are actually pretty decent. The four "Mission Gamma" books that follow are fucking garbage, and it only gets worse from there.
The Voyager relaunch is similar - the first two Christie Golden books are actually pretty decent. The next two are dogshit.. Then Kirsten Beyer took over, Ichebed everyone, and it's just been violent melodramatic garbage since then.
Honestly, if someone asked me what Trek books to read, I just tell them to read anything published in the '90s for some mild entertainment, and ignore the rest.
