Quick recap
Six months later, the Greek campers arrive at Camp Jupiter aboard the Argo II, the flying ship Leo built. The seven demigods of the prophecy are together, but the Romans think the Greeks are attacking, and tension boils over. The seven flee toward ancient Rome across the Mediterranean to stop Gaea from waking. Annabeth carries a challenge from her mother: follow the Mark of Athena and recover the goddess's giant statue, the Athena Parthenos. The trip runs through Charleston and the Atlantic, with Nico held by the giants. In the final stretch in Rome, the crew loses more than it expected.
