The Lost Hero

Heroes of Olympus

Content Ratings

Mild Romance

Piper's feelings for Jason and a developing attraction between the two are a warm thread through the novel; the romance is sweet, handled with Riordan's characteristic lightness.

Light Themes

Memory loss and questions of identity are central to Jason's story; the emerging threat of Gaea adds longer-term stakes; the tone remains warm and ultimately optimistic.

Mild Violence

Quests involving monsters, giants, and the forces of Gaea create exciting fantastical combat; violence is consistent with the series' tone.

Synopsis

Jason Grace wakes up on a school bus with no memory, flanked by friends he doesn't recognize, and quickly finds himself at Camp Half-Blood with two new companions—Piper and Leo—as they embark on a quest to rescue Hera and prevent the rise of the earth goddess Gaea. The opening of the Heroes of Olympus series introduces new demigods alongside familiar ones and expands the mythology to include Roman traditions.
