In 2106, Maida Sun possesses the ability to see the entire history of any object she touches. When she starts a job with a cultural recovery project in San Francisco with other psions like her, she discovers a teacup that connects her with Li Nuan, a sex-traffificked girl in a 1906 Chinatown brothel, and with Nathan, a tech-designer and hedonist of 2006.

A chance encounter with a prominent political leader reveals to Maida his plan to contain everyone with psionic abilities, eliminate their personal autonomy, and use their skills for his own gain. Maida is left with no choice but to join a fight she doesn't feel prepared for, with flashes of the past, glimpses of the future and a band of fellow psions as her only tools. She must find a way to stop this agenda before it takes hold and destroys life as she knows it. Can the past give Maida the key to saving her future?
