I fucking love these books. They're always so fun and exciting. 
The book starts off with Percy burning down his new high school which his mother's new boyfriend got him into. He teams up with Rachel, the Mortal with clear sight who ends up stirring Annabeth's jealousy. 
Annabeth and Percy kiss in this one but no further romance happens and the book ends on a sad note. Now that I think about it, does Annabeth feel rejected? because they never discussed the kiss which she initiated. 
I liked how Nico slowly comes to his senses in this one, even though it might've been too simple, I dont know I wanted more drama. But when his and Percy's scene in the last chapter makes it clear that he's not a part of Camp Half-Blood, it made me really sad. I love Hades :( 
Percy learns to summon water from his guy. Annabeth finally gets her quest, which ends in tragedy because she lost Luke, her true love. 
 Grover finds Pan who wants to die. Percy and Tyson have a great relationship in this one.
It's 5am and I don't feel like continuing to write the review.
