Hodgson is most widely known for two works. The House on the Borderland (1908) is a novel of which H. P. Lovecraft wrote "but for a few touches of commonplace sentimentality [it] would be a classic of the first water ".  The Night Land (1912) is a much longer novel, written in an archaic style and expressing a sombre vision of a sunless far-future world. These works both contain elements of science fiction, although they also partake of horror and the occult . According to critical consensus, in these works, despite his often laboured and clumsy language, Hodgson achieves a deep power of expression which focuses on a sense not only of terror but as well of the ubiquity of potential terror, of the thinness of the invisible boundary between the world of normality and an underlying, unaccountable reality for which humans are not suited.
