Esa Waters' first memory is from three years ago when she was found walking around the scene of a deadly car accident. That was the day she simply appeared. A girl with no family and no history. Then a mystery boy appears at her school. He says he knows her and questions what she is doing in the year 2010, a year decades before she was even born. As Esa returns home to the year 2105, she is reunited with others similar to her. Now she just wants to know what caused her to go missing for three years. Was it an accident or did someone intentionally try to make her disappear by hiding her in another century? If so, why and more importantly...who?
