This was a good read, historical fiction with some supernatural elements. Set in Scotland by Loch Katrine in 1856, where they are attempting to bring clean water to Glasgow through canals and tunnels. Isobel Aird is married to a doctor and they are living at the Loch. Suffering many miscarriages she finds solace in this will place. Then comes a strange man Robert Kirke, who is not as he seems. I visited this place so was keen to read this.
