Percy Jackson the young demi-god is back for his second exciting adventure in the bestselling series by Rick Riordan. You cant tell by looking at me that my dad is Poseidon God of the Sea. Its not easy being a half-blood these days. You mortals cant even see the monsters we have to fight all the time. So when a game of dodgeball turned into a death match against an ugly gang of cannibal giants I couldnt exactly ask my gym teacher for help. And that was just for starters. This is the one where Camp Half Blood is under attack and unless I get my hands on the Golden Fleece the whole camp will be invaded by monsters. Big ones. Can Percy survive the treacherous Sea of Monsters and restore order to Half-Blood Hill?
