Lost Hero sadly did not live up to my expectations, the only nice character is Leo. Piper is too full of her self and Jason is just plain clueless. But I have high expectations of Son Of Neptune because of Percy. The Percy Jackson books are the best of all Rick Riordan has written so far :) And Percy is a very strong character, so is Annabeth. I'm seriously looking forward to this book!
I had already read Percy Jackson Series, Kane Chronicles and The Lost Hero....these books are definitely of worth reading !!!! What I really like about the Hero of Olympus series is that it is more detailed than Percy Jackson Series and that I liked it. I am really waiting for Percy to see in action !!!!
