First, the fungus fed us. Now it's ready to feed. Biologist Jack Whitmore signed on to Moon Base Epsilon for the payday of a harvesting Fungus Lunaris, the moon mushrooms that turned Earth into a near-utopia. But when the newest crop bleeds midnight black, the crew’s routine transforms into a nightmare. The fungus isn’t mutating—it’s awakening.

Luminescent towers warp into predatory spires, friends fuse into living monoliths, and Jack realizes the infection is more idea than organism, rewriting flesh, thought…even starlight. Cut off from Earth, he faces an impossible escape a base that’s become a bio-cosmic altar, or sacrifice what’s left of his humanity to keep an ancient hunger from reaching the world below.

Perfect for fans of Jeff VanderMeer and The Thing, Fungus Lunaris is a claustrophobic cosmic-horror thriller where every breath could be your last, and every spore might be the universe staring back.
