This book may be my least favorite book in the Percy Jackson series so far. I'm not going to say I didn't like it, but there was so much happening during the quest in this book that it was really hard for me to keep up. Don't get me wrong, I liked meeting all the new characters in this book and the role they play in the battle of good vs evil. I just felt that Percy didn't grow much in this book. This book may be a lead up for the next book. I still liked it and enjoyed the adventure as it gets even more dangerous for the half-bloods. I look forward to reading the next book.
