Bored with the distractions of London, Judy Cameron insists on taking herself, her parents and her fiance to remote Glen Suilag in the Scottish Highlands. Leaving behind the busy whirl of the capital, she becomes absorbed in an unknown and yet strangely familiar world.

As Judy explores the house and glen, secrets begin to unravel and questions arise that she must find the answers to. Why does the strange house feel so familiar? How does she know the laird, Ian Macdonald? Why does she feel so terrified of the middle window in the parlour? And who is the mysterious Judith who haunts her dreams?
