This story is the second book of three books in the series. This book is about when Percy goes back to school. Some strange things happen, but when he heads back to Camp Half Blood, he gets some disappointing news.

I personally like this book better than the others in the series because it is an action packed book with lots of good words to keep the reader interested.

The plot of the story is that Grover goes missing and Percy must find him. Percy is an ordinary boy but he is also a half blood, it means that they’re half God, half human. He can control water with his mind. My favourite part of the book is when Percy plays dodgeball with Giants!

The theme of this book is that Percy has to find a Balance between being an ordinary boy and the son of Poseidon.

I would recommend this book to other people because it is very enjoyable especially if you like action.
