An ordinary road in a town like yours: bus routes and red-brick houses. A dank narrow alley, easy to miss, even when you're looking for it. A small black metal door set into the wall: no handle, no keyhole, but at your touch it opens onto a sunlit garden, sloping up to a house that doesn't quite make sense... ...Go through, and the door closes discreetly behind you. In David Mitchell's exhilarating new novel, five "guests" separated by nine years enter Slade House for a brief visit-only to vanish without trace from the outside world. Who draws them to the heart of Slade House, and why is the house missing from maps? Beginning in 1979 and ending in 2015, these five interlacing narratives will enchant Mitchell's readers, old and new, with a signature blend of mystery, realism, and the supernatural.
