Thirteen doors, thirteen hauntings. News reporter Joe Baxter has a plan.

His idea is simple - to use his newsroom contacts across England to find thirteen haunted places to stay, and then record his experiences in a book. From an abandoned cinema to a dank pub cellar, from a World War Two airfield to a lonely, landlocked cruise liner, Joe is prepared to spend long nights in the cold and dark, but has no idea what he is about to unleash.

For, as he endures increasingly dangerous vigils, meeting a succession of gruesome, tragic and terrifying spectres, a terrible truth begins to emerge.

Something - or someone - is reaching out to Joe, awakening long-buried memories of his father's death, a dark family secret and his teenage brush with madness. And then there is Wilko, the imaginary friend who haunted his childhood. After decades of silence, Wilko has found his voice again...

A spine-tingling supernatural mystery entwined with chilling ghost stories, 13 Doors places the reader at the dark heart of the moment, from gut-wrenching action to eerie vigils.
