After the earth-shattering cliffhanger epicness that was Deity and the emotional heartbreaker that was Elixir, I had to immediately dive into Apollyon as soon as I got it. And like always, that was both a good thing and a bad thing. 
 Good Thing: It wasn't that long ago that I read Deity & Elixir so I didn't have much to remember (not like I forget much of this series anyways because I'm so obsessed). Apollyon was FILLED with Aiden and Alex to my heart's content, I was basically the greedy kid in the corner savoring each and every line where their relationship progressed. 
 Bad Thing: I have to wait until FREAKING DECEMBER to know how it all ends! Why, Gods, why?! Why must you torture me so?! Although not a cliffhanger ending, it was still one of those endings that had me flipping the pages, pointlessly wishing there was just a smidgeon more for me to read. I seriously do not want this series to end! 
 I've said it before, I'll say it again - Oh, Aiden! Gods, can I honestly love this guy more?! I have yet to "meet" a fictional guy that I love more than him. The dude is brave, caring, smart, strong, and compassionate. He's sexy as hell and fiercely loyal. I could name about a hundred adjectives to describe the awesomeness that is Aiden St. Delphi! His relationship with Alex is tested a lot throughout the book and you really start to see the strength in it and just how deeply these two care for each other. Their love is just that. Love, in its truest and most beautiful form. There's also quite a few smexy times thrown in there for those who love it, like me (LOL), and I really loved it. There is this one scene when Alex and Aiden journey into the underworld that is just, PERFECT, sigh...I can't even put into words. They are easily my favorite bookish couple, without a doubt. 
 There is hardly any of Seth in Apollyon, which kind of surprised me. I expected to see more of him, but I can see that Jen is holding off for a really juicy confrontation in Sentinel. I honestly still have hope for Seth. He really is a good guy who is being misled and high on power. I fear for the ending though because we all know that there can be only one Apollyon. Gods, just writing this is getting me even more pumped for Sentinel! 
 Alex's fate just keeps getting more and more twisted as she learns exactly what it means to be the second Apollyon. In finding a way to stop Seth, she uncovers a deeper truth to her destiny and what exactly the Gods have in store for her. She's always been a strong female lead, my go-to heroine when asked, so I love seeing how she develops even more mentally and physically in Apollyon. She learns to harness her powers and perfect her fighting skills, while also seeing the "bigger picture" in this epic war of the Gods. She's also always been compassionate and a determined believer for Half-Blood rights, and you see a lot of that shine through here. 
 The secondary characters! I love them all! It's not very often that I really like all the characters in a book/series, even the ones I hate (love to hate). The Covenant series is an exception. We see a little more of Deacon, Lea, Marcus, and plenty of others here. Some of Gods even make appearances as well, old and new. They are truly an exceptional cast and it was definitely a thrilling ride watching them at odds with Alex as the Seth-obsessed Apollyon and when they venture away from their safe haven to a place that holds quite a few unexpected enemies. I'll admit, I totally figured out who was behind it all, but watching it all play out?! Now that was freaking awesome. Oh, that one scene where Alex and Aiden look at each other (you'll know when you get to it), *tear*! 
 Whereas Deity unleashed a pivotal point in this saga, Apollyon sets up the scene for what I'm sure will be one hell of an epic conclusion. This series has yet to disappoint me. Why do we have to wait until the end of the year to see how it all ends?! I would seriously sell my left kidney to read Sentinel RIGHT NOW! You hear this, Kate?!
