These walls have watched the witches; the witches have watched the world. These walls now turn against them -- some evil's been unfurled. . . . The one thing any Halliwell witch has always been able to count on is Halliwell Manor, the ancestral home of the Charmed Ones and one of San Francisco's historical landmark homes. The grand old house has sheltered generations of women, and bits of Charmed history are practically built into the walls. So when the Manor seems to have turned against its inhabitants, needless to say, the Halliwell sisters start to worry. It begins simply: The hot water heater is broken. No big: Leo's great around the house. But this is no simple plumbing problem. Soon, the Manor seems to be messing with the girls, Leo, and Wyatt in increasingly malicious ways. Thankfully, the Book of Shadows has created a safe zone for itself in the attic. But the Charmed Ones can hardly live up there forever. . . . Can they find out what's turned their safe haven into an evil lair before it's too late -- for the Manor, and for them?
