Along the way, they land at the island of Circe, a magician. She changes Percy into a guinea pig. Annabeth saves Percy and they manage to leave in a ship. They pass the land of the Sirens. Annabeth knows that the Sirens tell a person of their innermost wishes. She tells Percy that she wants to listen to the Sirens' songs. So, she asks Percy to tie her to the mast of the ship. But, Percy forgets to remove her knife. So, she manages to free herself. She almost manages to reach the land. However, Percy saves her. This way, he learns what that the Sirens' song made Annabeth see. The monsters showed her parents together again and Luke having become good. They are all having a picnic, in a new Manhattan, built by Annabeth. From the Sirens' song, Annabeth understands that her fatal fault is hubris (arrogance or too much pride).
