When fifteen-year-old Xander and his family move into an old, abandoned house in the middle of a dense forest outside of a small California town, they discover that not only are some of the rooms portals into other places, but that malevolent forces are at work.

With their mother still missing after going through a Civil War time portal in their spooky house, and their father in jail under a false accusation, Xander, David, and their younger sister continue to try to bring their mother back, now with the help of an old relative who has turned up unexpectedly.

To save the world from destruction, rescue their kidnapped mother, and battle the evil Taksidian, the King siblings try to control the mysterious portals in their house that send them to different time periods.
