Does anyone know when a fifth book to the Percy Jackson and the Olympians series will be published??? I just finished the 4th book which came out today. It was actually pretty good and i have a new favorite character. I really can't wait until the fifth book is published, because i think it is probably the last one in the series. Any comments or answers to when the book comes out? Any comments on what you thought of the Battle of the Laboriynth?
