There are two series of the books. The Sea Of Monsters  is the second book of the first series. The main characters are Percy Jackson, son of Poseidon, Annabeth, daughter of Athena, and Tyson, son of Poseidon. Tyson is a cyclops. A cyclops is a human that has one eye and is immune to fire. Percy and Annabeth are half-bloods or also called demigods. A half-blood is someone that is half human half god. They are made by a human and a god.

They move around in the book so the book isn’t happening all in one place. Percy and his friends need to go find something to heal Thalia’s tree. Thalia’s tree is a tree that protects camp half-blood. Camp half-blood is a camp for only half-bloods. Really it’s impossible for a mortal to come through to the camp unless one of the half-bloods say their first and last name and who they let into the camp. So back to saving Thalia’s tree. Thalia’s tree has been poisoned by we don’t know who. The only thing that can save Thalia’s tree is the golden fleece. The golden fleece is a fleece from a gold sheep.

I really enjoyed the book because it’s different from other books. The book is different from other books because it has a lot of action. And not a lot of books have a lot of action. My favorite part was when Tyson punched the bull smack in the face! The bull was evil. I recommend this book to people who like action I rate this book 4 ½.
