Sundial

Very hard to review this, as more or less any description of the setup, let alone the plot, is going to be heading towards spoiler territory. But rest assured if you relish the dread of approaching disclosure and the stomach dropping clunk of understanding as it becomes clear, and hey I know you do because you're a good horror fan, you're going to lap this up. It's intense, claustrophobic and genuinely monstrous in places. Like all the best gothic fiction the setting is as much a character as any of the actors in the novel, and long after you've finished you will feel the sunbaked desolate expanses of the desert and the cool dark spaces of the house on your skin - at least on the bits of it that aren't still tingling from the hammer blows of revelation and twist that build the climax.
