Three years after discovering a startling truth about her heritage, Maia Peterson thought it was safe to return to Olympia - a hidden world of fearsome giants, enchanting nymphs, and other creatures and characters from Greek mythology - if she wore the magic bracelet given to her by Zeus, lord of the gods. But when the queen of the Amazons, a tribe of powerful warrior women, falls prey to a mad, bloodthirsty demi-god, Maia risks Zeus’s protection to fulfill a promise once made by her long-missing father. Side by side with the mightiest of combatants, Maia is pitted against an old rival who wants nothing more than to see her fall in battle - all under the watchful eye of forces that hold her to be the key to the future of Olympia… and the world she calls home.
