The Mark of Athena

For the first time, the Greek and Roman demigod camps are face to face — and nearly tear each other apart. Seven heroes: Annabeth, Percy, Jason, Piper, Leo, Hazel, and Frank. One ship. One mission: sail to Rome, close the Doors of Death, and prevent the giants from awakening the earth mother Gaea before she destroys everything. Easy.

The third Heroes of Olympus book is the series at its most ambitious — juggling seven protagonists, two mythological traditions, and a plot of genuine epic scope, while keeping every character distinctly themselves and the emotional stakes completely real. Annabeth’s quest to follow the Mark of Athena — solo, into the oldest and most dangerous part of Rome — gives her the heroic centre stage she has long deserved and reaches a climax that left a generation of readers gasping.
