Overall, I loved this series. Dennard's characters are compelling, the plot relentless, the moral quandaries interesting, the debates over them push the story forward instead of bogging it down.
The ending is undoubtedly bittersweet, but satisfying in the sense that yes, I am ready to say goodbye to these characters and move on to what's next. You know how some books keep you in their world after you're done and make it impossible to pick up the next book for a few days? This one doesn't do that, but oddly I'm not at all disappointed about that. Everything feels wrapped up, bittersweet, but with closure.
I'm looking forward to reading more from this author.
