On a small island in a remote corner of northwest Scotland lies Maundrell castle, owned by its wealthy namesake family for centuries—until now. Edwina Nunn is shocked to learn a relative she never heard of has bequeathed the castle and its land to her. What awaits Edie and her teenage daughter, Neve, is even more startling, for the castle is home to a multitude of ghosts.
Yet there’s a strange beauty in the austere architecture and the eerie, bloody waters of Loch na Scáthanna, the Lake of Shadows. Beguiled by a frightened ghost who gazes longingly out of the castle’s windows, Edie and Neve are drawn to the legends shrouding the island and the mystery of the Maundrell Red—a priceless diamond that disappeared decades before.
