If someone had told 12-year-old Percy Jackson yesterday that he was the son of Poseidon and that ancient Greek myths were actually true, he would have burst into laughter. Today, Percy finds himself in a dire situation. He narrowly escaped being ripped apart by a fury, discovered that his closest ally is a satyr, and realized that he is a demigod. But the stakes are even higher: he stands accused of stealing Zeus's lightning bolt. With only ten days to uncover the true culprit, the looming threat of a war among the gods hangs over him. The boy and his friends, suspecting Hades was plotting against them, embarked on a dangerous journey to the kingdom of shadows, leading to an unexpected outcome.
