Percy and Tyson meet up with Annabeth, who asks if Percy’s also been having the dreams about “Big trouble at camp” (27). She knows something’s wrong and that they need to get to Camp Half Blood as fast as they can. Monsters have been chasing her since she left Virginia, and she wonders why they haven’t attacked Percy until she realizes Tyson is a cyclops and has been keeping monsters away.

Annabeth hales the Chariot of Damnation, which is a taxi driven by the Gray Sisters—three ugly old hags with one eye and tooth between them. Despite having a taxi service, the sisters drive terribly, made worse when they get into a brawl over who should have their eye. Percy questions whether they actually know anything, and one announces she knows “the location you seek” (33). The other two scold and beat her up for offering dangerous information, which makes the eye go flying into the back seat. Percy retrieves it and threatens to throw it out the window unless the sisters tell him what they know. They give him a list of numbers: 30, 31, 75, 12, and nothing else. Percy returns the eye so the taxi can stop at camp.
