It's over. It's actually over. This is one of those series that I can't even bear the thought of never getting another book, or another story about Alex, Aiden, Deacon, Luke, Marcus, Solos, and all of those other wonderful characters. This series means the world to me, and I am beyond thankful for having read it. It is by far one of the best series I have ever read and it (along with the Lux series) is my go-to comfort book. There are so many scenes that I constantly go back to and read all the time and they never, ever get old. 
 This was honestly one of the most emotional books I have ever had the great pleasure of reading. It ripped put my heart, shredded it up into a million pieces, and then stomped all over it over and over and over again until I thought that I wouldn't be able to feel anymore pain in my heart. 
 Now that I've finished it, I can't concentrate on anything because I just can't stop thinking about everything. So much happened and all so fast and unexpected that I can't believe it's over. 
 The few section of the book made me cry like a baby, which I don't normally do all that often when I'm reading. However, it just killed me, it really did. As I said, these books mean so much to me, more than I could ever out into words. Now that they're finished, I don't know what to do with myself. I can't imagine a life in which there are no more books in this series. It sounds overdramatic, I know, but it's the truth. 
 I'm left with so many questions about what happens to all of the characters at the end. I was honestly expecting an epilogue, and I don't know what to do sine we don't have one. 
 (view spoiler)[ What happened when Aiden went to go see his parents? 
 What exactly did Lea, Olivia, and Alex's mother say to her when she arrived in the Underworld? Why did we only see a snippet of a conversation with Caleb? 
 What happened tov Alex's dad? Is he okay? 
 How to Solos and Laaden respond to Alex's 'death'? What about Deacon and Luke? And Alex's father? Give me more details Apollo! 
 Will Alex and Aiden be able to have children now with this whole demigod and six months in the Underworld and six months in the real world situation? I know Aiden really wanted to have kids based on hoe excited he was about Alex's possible pregnancy. 
 What about the weekly slumber parties that Alex, Aiden, Olivia, Deacon, and Luke were going to have after everything was over? I was so looking forward to seeing one in the Epilogue! 
 When they go back to the real world, what will Alex and Aiden do? Will they be sentinels, or will Alex finally fulfill her dream of being a zoo keeper? Where will they live? 
 I NEED ANSWERS JENNIFER ARMENTOUT, I NEED ANSWERS! 
 I know that there is a spin-off series featured around Seth, which I will most definitely be reading because I fricking love Seth, but from what I understand, Alex and Aiden don't make any appearances. And that's really depressing. They are characters that I've grown to love more than I could possible ever express and it hurts so much to never hear anything new about them. It hurts so, so, so, much. 
 This is definitely one of the most memorable series I've read, and I know that it will stick with me forever. And for that, I'm grateful. So thank you, Jennifer Armentrout, for creating this story that has never failed to make me smile, cry, laugh out loud, and feel every wonderful emotion that I could only hope a book would bring to me.

 Seriously, I'm not exaggerating It's just THAT good. But don't take my word for it. Go read this series for yourself. Trust me, you'll be happy you did. (hide spoiler)]
