Comraich - Gaelic for Sanctuary - that's what this ancient fortress of a house in the Highlands of Scotland has offered its generations, a haven from the world beyond.

The nesting instinct kicking in, a pregnant Jessamin decides that Comraich, which she shares with her partner Fionnlagh Maccaillin, needs refreshing. Getting to work in one of the spare bedrooms she makes a startling discovery, one that pulls her into a world of the intense and disturbing passions of others that have been here before.

Jessamin has to decide.

Will delving deeper into Comraich's history bring hope and peace to this troubled house or return her to a darkness she's only recently left behind?
