Heroes of Olympus Books in Order
The Heroes of Olympus is a five-book sequel series to Percy Jackson and the Olympians. Set in the same universe, it follows seven demigods—including Percy Jackson and Annabeth Chase—on an epic quest to prevent the awakening of Gaea, the earth goddess. The series introduces the Roman counterpart to Camp Half-Blood, Camp Jupiter, and expands the mythology to include Roman gods alongside the Greek pantheon. With higher stakes, more complex storylines, and an ensemble cast of heroes, the series culminates in an epic battle to save both camps and all of Western civilization.
