Once again, Jennifer L. Armentrout delivered! She is officially one of the best series authors I've ever read. She clearly understands how to build upon an existing story, develop characters in a likable way, and keep a reader vested and thirsting for more. In fact, I'd say Armentrout's books only get better and better as a series progresses. I saw this in her "Lux" series, and now I'm seeing it in her "Covenant" series. 
 Now, as for "Deity"...I'm going to keep it short and sweet. I loved it. There was plenty of laughs, plenty of action and plenty of heartwarming (and breaking) moments. There was also resolution to a couple of central conflicts that needed to be resolved by this point. One of my book pet peeves is when an authors drags out a conflict for-evvvv-ver; almost like they're afraid if they solve it, there won't be any story left to tell. No problem with that here. The conflicts solved were replaced by new, interesting ones that drew me in to the story deeper, and increased my enthusiasm for Alex's harrowing tale. 
 When I reached the final page of "Deity" I was completely satisfied and eager to move on to the next in the "Covenant" series, "Apollyon".
