Kids today have no respect!!!
Sarah Field lives alone with her dad, a teacher at her school. The two of them share a close bond and, unusually, both have the same birthday, which they also share with Sarah's grandfather, who died when Sarah was small. Sarah knows very little about her grandfather, and her dad insists on keeping it that way.
However, one night, Sarah finds her dad acting mysteriously and also hears strange noises after her dad has gone out. Sarah's friends come to the rescue to help her investigate, and they make a shocking discovery. Someone is living in the attic! And that someone is none other than Sarah's grandfather! But, this is no ordinary grandfather...
With the discovery of her grandfather comes the question as to whether Sarah has the power to give life to the amulet - the Telum Deos - that will help to fight the forces of darkness.
