Percy discovers that there is a problem in the mongrel camp. The magical border forces that protect the camp from monsters have fallen. The tree it supports has been poisoned by an unknown enemy. It is only a matter of time until the monsters overrun the camp. The only way to save the camp and cure the tree's poison requires him to sail with his friends into the sea of monsters!
