But one morning, he wakes to the news that his older brother, Magnus, has gone missing on Shetland. Mum has already booked tickets to go and search for him. Theres good reason to be worried. Five years ago, Viggos dad, Jonathan, went off grid in the same location and disappeared. He is now missing presumed dead. Viggo has no option but to go to Shetland with Mum - but from the moment they set off, hes troubled by strange visions: images of armed warriors, mythical creatures and Viking longships. And then they encounter Leon, a mysterious wandering musician who attaches himself to them and proves impossible to shake off. Once on Shetland, the search for Magnus begins in earnest and Viggos troubling visions start to intensify. Soon he is finding it difficult to separate fact from fantasy and who knows what terrors lie in wait for him deep beneath the ground?
