Trident of the Third

Percy Jackson and Annabeth Chase have settled down. After defeating Kronos and Gaea and saving the world multiple times, they have decided to start their freshman year of college together in New Rome. Everything changes after their peaceful year, and they decide to visit Camp Half Blood over the summer. They realize their worst nightmare becomes true: Chaos awakens, and wants to take over the world-- again.

With a new prophecy and quest, the demigods must face the creator of the universe and his Primordal Gods.
We better grab out Riptide, because here we go again.
