When Kate's grandmother presents her with a mysterious blue medallion and mentions time travel, the sixteen-year-old believes the old woman is hallucinating. But it all becomes terrifyingly real when a murder from Kate's past wrecks the foundation of her present-day life. That medallion is suddenly the only thing keeping Kate from blinking out of existence.

Kate discovers that the 1893 murder was part of something far more nefarious, and her inborn talent for time travel puts her the only person who can change the future. Risking everything, she travels back in time to the Chicago World's Fair to avert the murder and the subsequent chain of events.

Changing the timeline incurs a human cost. If Kate succeeds, the boy she loves will have no recollection of her. And, whatever her motivations, does Kate have the authority to control the fate of the entire world?
