Outpost on Io is a science fiction novella by Leigh Brackett, written in the early 1940s. The story follows Chris MacVickers, a prisoner in a labor camp on Jupiter's moon Io, as he struggles against the oppressive Europans, an alien race that controls his fate. This work explores themes of survival and resistance in the face of inhumanity, making it a notable example of early science fiction that addresses human-alien encounters and the brutality of war.
