The Sea of Monsters (Percy Jackson and the Olympians, Book 2 of 5)

SUMMARY:
You can't tell by looking at me that my dad is Poseidon, God of the Sea. It's not easy being a half-blood these days. You mortals can't 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 couldn't exactly ask my gym teacher for help. And that was just for starters. This is the one where Camp Half Blood is undernbsp;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 Monstersnbsp;and restore order to Half-Blood Hill?
