This book picks straight up from The Lost Hero were it is shown that Percy has lost his memory. All through the book Percy is trying to get his memory back. Other friends are trying to find Percy as well. Also a traitor is trying to kill Percy.
There are many things I like about this book. The first thing is that there always funny moments that would always force you too laugh. Another thing I like is that there is suspension that makes your jaw drop. The final thing I like is that it is very creative.
However there are some things I dislike about this book. There are some moments in the book that are repeated over and over again. Another thing I disliked about this book was that the book was to short being only 400 when the lost hero was 500. The final thing I dislike about this book is that Percy's character traits have changed to much.
Many people claim that the book is very bad. To that I respond could you write better? Some people claim this book is a wannabe Harry Potter. To that I respond it is a completely different story line.
All in all, this book was great and Rick Riordan has done it again bringing back Percy almost how he was before. It had it's ups and downs but overall it was amazing. I can't wait for the next book and that it has elements such as this.
