Fans of Catriona Ward and Stephen King will find plenty to enjoy in this biting horror novel where not all is what you see... or hear.

In 1983, artist Tony Mathias began work on a new installation – a collage of visuals and sounds, exploring the history of the abandoned RAF base on Warden Fell.

Tony was a gentle soul, a devoted family man. But after visiting the site to tape-record the sounds there, he killed his wife and children, set their home on fire, and turned his gun on himself. The closest thing to a reason why were two words, scrawled on a fire-blackened wall: WORLD’S END.

Decades later, true-crime podcaster Cally Darker begins researching the murders, aided by Tony's actress sister Stella. When she finds Tony’s recordings, she thinks she has a fantastic exclusive – perhaps even a chance to solve the mystery. But Warden Fell, for centuries the focus of folklore, mysteries and fearful legends, has a far older and more terrifying story to tell.

Cally’s about to learn what turned Tony Mathias into a killer. But it might be too late to save her.
