As long as you're OK with the fact that they don't line up entirely with the Paramount+ series, then yes I'd highly recommend them. They are what first got me into Trek Lit, before them I had only read the New Frontier books, but as a huge DS9 fan, I couldn't resist once I found about them, and then they became my gateway into the larger Novelverse as it grew from that point on. The whole Avatar - Unity era is one of my favorite series ever, they're great books, and did a fantastic job of continuing the story on past the show.
