The Sea of Monsters
By Rick RiordanAfter all the chaos of last summer, Percy finally gets a chance to be a normal middle school kid--at least, he can pretend he does. Along the way, Percy also discovers that one of normal human friends isn’t as normal as he may seem. Suddenly, while playing dodgeball, monsters appear and threaten Percy’s life. Annabeth comes to his rescue just in time, and they both make their way back to Camp Half-Blood only to find out that it is in trouble. Thalia’s tree, the one that holds the spirit of Zeus’ daughter, is ill.
