When Percy Jackson steps into Camp Half-Blood, he expects monsters and gods. He doesn't expect Cabin 7 to defy the ancient traditions, nor does he expect a god who actually answers his children's prayers. Apollo is not the arrogant deity the myths described. He is a father who lingers in the shadows of the camp, a protector who whispers through golden luck, and a player in a divine game of politics that even Zeus fears to interrupt. As Percy is drawn into Apollo's golden orbit, he begins to see the cracks in the Olympus he thought he knew. Through dreams of a forgotten past and a bond that defies the laws of gods and men, Percy realizes one thing: The myths were a lie. The truth is much more dangerous.
