This is the second book of the Percy Jackson series. A lot of important events happened in this stories. it started off with a competition, it showed that Percy Jackson had a new competitor, and she's the daughter of war, Clarisse. She's really tough, strong and clever, and very competitive, likes to tease Percy Jackson about that all he did (In the lightning thief serie) was because of luck. And then, he found out that he has a step brother, that is half god, half cyclops. During a usual day, they heard something huge, sounds like something is bumping the wall of Thalia (the daughter of Zeus). It brought a great disaster in the camp, because without that wall, anything, monsters, beasts can go in and destroy the half bloods. So they decided to send a group of the strongest kids to go find the golden fleece, known that it can heal anything. Although the directors sent Clarisse, and another half goat, but Percy thinks that he has the responsibility to save the camp, because of the prophecy he heard. And so he went on an adventure to find the golden fleece, to save the Olympus. It's also very intense to read, the scenes reveal in your eyes vividly, a really good book to read, it's also pretty funny. I really recommend this book the kids in any age, because it's not too hard, and it's interesting, have fun reading this fantastic book!
