I like these books, they're good fun. In this one Camp Halfblood is in serious trouble. Thalia's tree is dying and monsters are invading the camp - only one thing can save it - the golden fleece. But Percy isn't allowed on the quest to bring it back - will that stop him?
Chiron's been fired, his replacement is a disaster. Mr D doesn't care about camp (even more than in the first book).
So, what happens - well Percy finds out he has a half brother. Grover nearly marries a cyclops, Percy becomes a Guinea Pig (really) and Annabeth has her wildest dreams come true - oh and Luke rides the seas in a cruise ship with a coffin.
Did I mention that Thalia makes an appearance?
Bring on the next one.
