Percy Jackson: Sea of Monsters

Percy Jackson has had an unnervingly quiet school year. But then he discovers that the magical borders protecting Half Blood Hill are failing. Unless something is done, the camp will be attacked by demons and monsters. The only way to restore power to the camp's borders and to save their home is to find the mythical Golden Fleece. And the only who can undertake this dangerous quest are Percy and his friends. Embarking on a treacherous odyssey into the uncharted waters of the Sea of Monsters (known to humans as the Bermuda Triangle), they battle terrifying creatures, an army of zombies, and the ultimate Evil.
