Apollyon is full of action. The first few chapters are awesome. Alex is back to herself but she is more mature in this book. 
 Aiden has proven his love for her on more than one occasion. They spent most of the book together. All the usual suspects are back. 
 The gods are choosing teams. Apollo is always awesome and funny. I still don't know what the deal is between him and Deacon (can't wait to know what it is). 
 The new addition of more gods is interesting. A huge battle is lurking. 
 Alex and Aiden must go to the Underworld. Good and bad things happened there. 
 Also, we found out who is the god behind Seth and the destruction. 
 This book made me cry but also made me very happy. Can't wait for Sentinel. I love Aiden with Alex but I want Seth to be redeemable too. He has been used and I know he does care for Alex. I wonder if he is mad about what happened to her and who was the one who hurt her.
