A time-traveling fugitive has stolen Ava's body, her identity, and her life. What's more -- she's not alone. There are others, hiding in the past, secretly living among us, plotting to alter the future. Without her body, Ava is a virtual ghost, silent and invisible to the world. And, so far as she knows, she's the only one who can stop them and put the timeline back on course.
