In 1988, young American traveler Quincy Redding is trekking across the misty terrain of the Cairngorms, in the Scottish Highlands. She is destined for the infamous peak Ben MacDui, where she soon finds herself debilitated and at the mercy of a malevolent entity.

A darkly imaginative and harrowing tale, Prince of Earth spans 20 years, alternately following Quincy in her 1988 ordeal in Scotland as well as Quincy in 2008, when, as an adult, she begins experiencing strangeness that threatens her family and her life. Strangeness that may be related to what happened all those years ago.
