Ess Fremont and the Blue Lotus Society know the Originators have been infiltrated by Revisionists, their ancestral enemies in the quest to rewrite or protect history. The treachery has reached even to their headquarters, Sanctuary, an underground complex near San Francisco.

Problem: The Society can't contact Sanctuary, or risk putting power into the enemy's hands. Yet Ess must go there to claim her heritage and learn how and why her grandparents vanished seven years ago. All her answers, and a vital weapon in the battle against the Revisionists could lie in her grandparents' vault -- and Ess herself is the key to open it.

Solution: Ask her family lawyers to "turn her in," and on the train ride cross-country, begin her education.

The journey launches revelations that threaten everything Ess knows as truth. As she uncovers schemes within lies within treachery, the fulfillment of her family's destiny rests heavy on her shoulders.

Who can she trust when her own grandparents blocked her memories, and the means to save or destroy them all are hidden in the vaults of her mind?
