Lisa Miller just lost her parents. This wasn't the first time, though. She's actually gone through this many more times than she would like to admit. She finds that she is immortal, or so she assumes. While she's mourning for her loss, a certain Spanish boy sees her and accuses her of being his long lost little sister. Finding that this could be what's been missing in her life, she accepts this accusation and enrolls in the local private school to see what more of her past she may uncover.
