AT is amazing and likely my favorite contemporary author other than James SA Corey (I know two authors, lol). The Final Architecture after reading The Expanse is a great ride. Im currently reading Bear Head and its so good, one of my favorites so far. I didnt realize its same universe as War Dogs but set later, so thats next on my AT list. Bee Speaker is being released this year as the 3rd book in that series, stoked!
