For Caisle�n T�g�la� and his wife, Eagna, the opportunity to live in the ruins of Dunnideer Castle seems like a dream come true. Caisle�n, a Scottish architect specializing in renovating old castles, has been hired to restore the ancient fort. Caisle�n enthusiastically moves his entire family into the building while he works on it.

At first, the couple's two children, Ch�ad and Geala�, share their parents' excitement. Geala� feels just like a princess as she works to turn the old castle into a home.

Then, strange things begin happening to every member of the T�g�la� family. Lights go on in the tower when no one is at home. Everyone hears unintelligible ghostly whispers, and the cellar is always warm. At first, the family tries to come up with rational explanations for these paranormal events. However, as Samhain approaches, the activity grows worse, and soon, bizarre-looking phantasms are appearing and vanishing without warning. Then, Caisle�n and Eagna fall ill with a mysteriously malady.

There's no doubt that something is haunting Dunnideer Castle. The real question is what these apparitions want with the T�g�la�s-and what the family will be willing to do to rid themselves of these ghostly visitors.
