Percy had power. He didn't know where he got it. What he did know is that if anybody ever found out about his power, he'd be majorly unavoidably screwed. For he had the ability to give anyone an unlimited amount of power- he could restore the gods to the way they were in their Golden Age, back when everybody sacrificed to them by touching them. The deeper and more.. intimately the touch, the more power he gives. The gods crave power. They always have. Zeus already is angry at Percy and wants him turned into a god simply because his pride will not allow him to be refused. So what will happen when they find out that their "Hero of Olympus" was a battery that never ran out of power, and all you had to do to access that power was to become intimate? Will they give into their lust for Percy's power and beauty? Will they show self-control and help Percy in his goal of not becoming an eternal concubine drugged so he wouldn't fight? Will Percy evade capture or will he succumb to his horrible fate? Gods turn against one another, in the bloodiest war since the age of Troy. "The face that launched a thousand ships" indeed.
