You DO NOT end a book like that! You just don't. You can't, it shouldn't be allowed! 
 This is up there with the ending of Opal, also by Jennifer L. Armentrout. Thank goodness I decided to read this series now that all of the books have been released. If I had to wait for the next book, I don't know what I would have done! Hide in bed until the next book came out? Probably. 
 Thankfully I was able to start Appolyon mere minutes after finishing this one and I'm now about half way done. (And oh my goodness it is fantastic so far.) 
 Something I really liked about Deity was how much more mythology we're getting in it. I found the other books didn't have quite as much of the mythology factor that I'd wanted, but this one definitely does! We get to see some gods and more of the powers from both them and our main characters. 
 (view spoiler)[ I will admit, I was pretty pissed when she died. I was kind of expecting the rest of the book and maybe a portion of the next book to be about her in the Underworld searching for a way out. There wasn't going to be any Aiden action in the Underworld! Luckily, the Underworld section was very short and I got my Aiden back :D 
 I loved the whole Apollo being Leon twist. I always knew that there was something up, but I didn't really expect this. But it was such a good idea; he is a very fun and bight character. 
 Have I mentioned how much I love Deacon before? Because I seriously do love him. And his possible relationship with Luke is just fantastic! I was not expecting that at all. I do love me a good plot twist. 
 And I am so, so happy with what happened between Alex and Aiden. I ship it so hard! Though I must say, they are ridiculously stupid, but hey, you do crazy things for love, right? (hide spoiler)] 
 This entire series is incredibly difficult to put down. It seriously takes a ton of effort, but I've somehow managed to do it a couple of times to sleep and eat. And I'm taking just a couple minutes to write a super, super quick review. Sorry, but reading is far more important than writing a decent review. You'll understand if you read this series. 
 And I am so grateful that I happened to have decided to read this series during my summer vacation, because if I read it during the school year I know that I would just neglect everything until I finished the books. 
 So, as much as I'd like to stay and chat about how great this book was, I must go read. I NEED MORE!
