A bone-chilling collection of H.P. Lovecraft’s hallucinatory visions of science, featuring the “exciting and definitive” (Danielle Trussoni) annotations of Leslie S. Klinger. Presenting nine fantastical works by one of literature’s “most critically fascinating and yet enigmatic figures” (Alan Moore), At the Mountains of Madness: And Other Tales of Weird Science is an essential volume of H.P. Lovecraft’s most visionary science fiction. In “From Beyond,” a reckless experiment ruptures the thin membrane separating our world from one teeming with interdimensional lifeforms, while “The Shunned House” tells of the battle of a young man and his uncle against a monstrous presence buried within an abandoned dwelling. At the center of the collection is the novella “At the Mountains of Madness,” in which a team of Antarctic researchers discover remnants of a sprawling, ancient civilization—and the chilling truth of its eventual demise. With Leslie S. Klinger as an indefatigable guide through Lovecraft’s peculiar, spine-tingling universe, and featuring an introduction by award-winning author Tamsyn Muir, At the Mountains of Madness is an essential edition for Lovecraft newcomers and devoted fans alike.
