 (4.5 stars) 
 aaaaaaAAAAAAAAAAAAAAAA. 
 dude. 
 Okay. Let's just start off by saying it took me nine days to read this. NINE DAYS. I think that's the longest time I've ever needed to finish a book. And on that topic, I would like to note that that's probably the reason I'm giving it 4/5 stars; usually, the longer I take to read a book, the less I like it/am invested. But this is a Rick Riordan book, so I couldn't not be invested. I felt like I had to drag myself through this, but I do have to say it's 100% worth it. I feel like in the future, if I reread this book, I would enjoy it so much more since I would have more time to read it and thoroughly enjoy it. 
 Honestly.... the ending. THE ENDING. I was NOT expecting that. I may or may not have shed a few tears because MAN. My baby Percy??? My girl Annabeth??? Oh God, I hope they make it out alive. 
 I thoroughly enjoyed allllll the mythology. I actually got some answers right on an Academic Team test because of Rick Riordan's books. It was all absolutely brilliant and I actually understand it! Before, I wasn't clear on half the stuff; now, I feel about 75% confident in some mythology. 
 I'm not in a huge rush to read the sequel, but I'm gonna read it ASAP. 
 Another reason I gave it one less star: I feel like it was missing that... spunk? Like, I hate to say this, but something just wasn't there for me. 
 A note: the character development and setting and plot and e v e r y t h i n g was A+. 
 I still reeeeeeeally enjoyed TMoA. I cannot say that this was a waste of my time. I love the characters, I'm so interested to see where this goes, and I am SO EXCITED to finally get all the fandom jokes. 
 Anyways, yeah. Probably could've enjoyed it more, but still loved it and L O V E D the ending.
