It started off like any other day, but for the tourists, staff and workmen at Willerton Castle it will end in terror. Because a storm is coming, a storm like nothing anyone has ever seen. A storm that will herald an attack by creatures this world has never encountered before. Will any of them survive? This new short novel of monstrous horror by the bestselling and award-winning author of Monsters (a British Fantasy Award finalist), the sellout Hooded Man and the award-winning Sherlock Holmes and the Servants of Hell, Paul Kane, comes with an introduction from Rio Youers (The Forgotten Girl, Halcyon) and cover art by Ben Baldwin.
