The Rook family run a little business: ghost hunting. And things have picked up recently. Something's wrong. It's been getting noticeably worse since, ooh, 2016? Bad spirits are abroad, and right now they're particularly common around Coldbay Island, which isn't even abroad, it's only 20 miles from Skegness. The Rooks' 'quick call out' to the island picks loose a thread that begins to unravel the whole place, and the world beyond. Is this the apocalypse? This might be the apocalypse. Who knew it would kick off in an off-season seaside resort off the Lincolnshire coast? I'll tell you who knew - Brenda. She's been feeling increasingly uneasy about the whole of the East Midlands since the 90s.
