Iceland, 1686. The brutal, lava-scarred landscape can swallow a man without so much as a volcanic gasp. Jón Eiríksson has just married his second wife in a year. But Rósa's new home in the windswept village of Stykkishólmur is terrifyingly isolated - the villagers are suspicious of strangers and fearful of something which they will not name. What is Rósa's new husband's secret, and why does the spectre of his first wife Anna haunt them so?
