Looking for Answers about Thomas Nelson House of Dark Shadows, Dreamhouse Kings Series #1?

When the Kings move to a new home in a new town, the house seems odd at first; but things get really strange when they realize that some rooms are portals to other worlds. The Kings face terrifying dangers within the rooms of their home, but it still seems like an adventure until people start coming out of the rooms and into the house. When one of the intruders kidnaps their mother, they must find a way to rescue her-but who would believe such a fantastical story?
