Connor 'Mac' McClymont is a man running from his past. In his converted ex-military ambulance, 'The Badger, ' the haunted investigator patrols the quiet backroads of Britain, seeking a peace he can never find. But when a string of chilling disappearances pulls him into the rain-lashed fells of the Lake District, he discovers a secret war raging in the shadows. His hunt for a spectral predator on Skiddaw uncovers a fanatical cult, their private army, and a ritual to awaken not one, but two ancient evils: a malevolent entity imprisoned in the mountain and a ravenous water-horse, the 'Eachy', in the lake below.Surviving the battle is only the beginning. Mac is drawn into a violent conflict with the territorial Fae, forcing him to broker a dangerous truce and become their Warden...a human enforcer on the violent border between worlds. From the haunted stones of Hadrian's Wall to the psychic depths of Bassenthwaite, Mac must confront human greed, ancient spirits, and monsters made flesh, armed with cold iron, silver bullets, and the hard-won lessons of a lifetime at war. For Mac, the Warden of the veil between worlds, the hunt is never over.
