Beyond Sleep is a novel by the Dutch writer Willem Frederik Hermans, published in February 1966. The protagonist, Dutch geologist Alfred Issendorf, has a geology dissertation in preparation, and embarks on an expedition to Finnmark, northern Norway, to verify his dissertation director's theory that craters in the local landscape were formed by meteor impacts rather than by Ice Age glaciers. Initially he is accompanied by a group of three Norwegian students of geology, but soon after he is isolated from his companions wandering on his own in a land where the sun never sets.
