At first I couldn't avoid the comparisons to Harry Potter. 
 As a Harry Potter lover I knew I would be very picky when reading this book because of everyone's reviews. 
 I'm going to be straightforward I liked this book. I did. Solid 4.5 stars. 
 What I didn't like about this book was that it didn't feel like Percy was twelve. Percy's narration doesn't feels like a twelve year old narration. Besides that I can't find any other dislikes to point out. 
 EXCEPT that scene w Medusa OMG HOW CAN YOU BE SO STUPID. But I mean heroes are always stupid at some point. 
 I lived Annabeth's character. I'm looking forward to read more about her. Also the mythology. I love greek mythology and it didn't disappointed me. There were scenes with a lot of climax and I love the ending!
