In The Son of Neptune Percy is trying to regain his memory all through out this entire book. Meanwhile they are on a quest to try to save Camp Jupiter from Gaea's army. Percy, Hazel, and Frank are going to try and complete this dangerous quest. They have to complete this quest before the Feast Of Fortuna, which is arriving very soon. If they don't Polybotes, the giant, will comes to destroy Camp Jupiter. Camp Jupiter's fate rests in their hands. I liked this book because it had a lot of action in it and I like books that have a lot of action. I really liked this book a lot because it has greek mythology, and before I read this series I had no idea what greek mythology was! Also I really like the authors writing style because it always keeps you on the edge of your seat.
