I got
Q&A, and finished it a few days ago. It was a very enjoyable story focused on Q. It didn't dethrone the Q-Continuum trilogy as my favorite Q book story, but it was good. I like how it tied his appearances together, but I also like how it didn't negate the idea that, sometimes, Q just likes to mess with Picard for no reason
It was actually a bit weird to get into the stuff on the Enterprise-E, because I'm used to the current novelverse stuff, so I wasn't familiar with the replacement Enterprise-E crewmembers in this book (Miranda Kadohata, T'Lana and Zelik Leybenzon), since they definitely weren't on the ship by the time the Typhoon Pact came around.
Looking on memory-beta, all three eventually went off the deep end, so good riddance to them (and I actually liked Kadohata). I also learned while looking them up that I should avoid
Before Dishonor like the plague

(I guess even Peter David can have an off day, the book sounds downright revolting and Peter David's stuff is usually excellent). Honestly, it seems like every book post Nemesis that featured the borg was terrible, although Before Dishonor seems like something I'd hate less for what the borg did and more because it has the three crewmembers in question doing something that could never, ever happen, especially on the Enterprise (outside of some kind of alien mind control of the whole crew).
So, overall, I enjoyed Q&A quite a bit, although knowing that a few of the newer characters are horrible, horrible people makes me wish they hadn't been given so much time in the book.
