What a book. I can honestly say I haven’t enjoyed a horror novel so much for a very, very long time. Beautifully rendered, flawed and relatable characters. A creeping sense of dread. Visceral violence dispensed by the cultish Red Folk. An ancient force straining at the barrier between the worlds. All grounded by a wealth of scientific data that makes you second guess your assumptions about what the Red Folk may (or may not) be summoning. A towering horror novel. Mr Neville, I salute you.
