The second in a quartet of exquisitely haunting ghost stories, Saltwater is set on the Isle of Stroma in 1896.
Sent to oversee the completion of a new lighthouse, Tom, a man of sense and science, is unprepared for the conditions on the island and soon learns there are some problems that science cannot answer, and some threats so ancient and strange, that nothing can keep them at bay.
