Pale Phoenix (Time Travel Mysteries)

Miranda isn't happy when sullen orphan Abby Chandler comes to live with her family. But Miranda's anger turns to shock when she learns the girl's horrible secret: Abby's parents and sisters were killed in a house fire in this very town--more than three hundred years ago. Somehow Abby survived the fire and has been living in a virtual limbo ever since.
Fifteen-year-old Miranda Browne, the extraordinary protagonist from Kathryn Reiss's first novel, Time Windows, returns for a new time-travel adventure.
