A dark spirit haunts an isolated Norfolk retreat in this unsettling and sinister historical horror set in the early 1900s, perfect for readers of Michelle Paver, Silvia Moreno-Garcia and Andrew Michael Hurley. Eustace Moncrieff is a troublemaker, desperate to go to war and leave behind his wealthy family. Shipped to Edenwell by his mother to keep him safe from the horrors of the trenches, he strikes up a friendship with Freddie at the behest of Doctor Chalice, the American owner of the Hydropathic.

As the two friends grow closer and grapple with their demons, they discover a body, and something terrifying stalking the woods. The dark halls of the spa are breached, haunted by the woodland beast, and the boys soon realise that they may be the only things standing between this monster and the whole of Edenwell.
