Garth Marenghi’s TerrorTome

When horror writer Nick Steen gets sucked into a cursed typewriter by the terrifying Type-Face, Dark Lord of the Prolix, the hellish visions inside his head are unleashed for real. Forced to fight his escaping imagination — now leaking out of his own brain — Nick must defend the town of Stalkford from his own fictional horrors, including avascular-necrosis-obsessed serial killer Nelson Strain and Nick’s dreaded throppleganger, the Dark Third. Can he and Roz, his frequently incorrect female editor, hunt down these incarnate denizens of Nick’s rampaging imaginata before they destroy Stalkford, outer Stalkford and possibly slightly further?
