Rick Riordan The Sea of Monsters
 
HALF BOY - HALF GOD - ALL HERO.
 
I've almost made it a year without one of my teachers turning into a monster. Just one more day to go. Surely even I can get through that?
 
Percy Jackson's life has been surprisingly quiet since he stopped all-out war on Mount Olympus. That is until an innocent game of dodgeball turns monstrously ugly. . .
 
Now Camp Half-Blood - the only safe place on earth for demigods like Percy - is under attack, and unless he can find the magical Golden Fleece, everything he's come to love will be destroyed.
 
Percy and his friends must journey into the Sea of Monsters to save their camp. But as the son of the sea god - how hard can this quest be?
