This book finds Percy once again trying to find success in a school only to have things once again go terribly wrong. He has his dodgeball game interrupted by a gang of cannibalistic giants and found out that the usually safe Half-Blood Hill is no longer safe and that he must help find a way to restore the safety.
There are parts of me that enjoyed this story more - it has many parallels with Homer's Odyssey, interacting with some of the creatures that are familiar to those who have read it (which I have about seven times). I like that Percy is still on a personal quest to discover who he really is, what all these events that keep forcing him to react really have to do with who he is as a person/demigod/kid. I thought the plot was well thought out, the commitment Riordan has to staying true to the ancient stories is admirable, and I was delighted with this reading experience. I'm hoping to get to the third very soon.
