The Slab Press presents Minerals: a series of exciting science fiction anthologies featuring handpicked novelettes and novellas from established and up-and-coming voices in science fiction. Each anthology will take on some of the quality of the minerals they are named for: beautiful, iridescent themed stories that could be as dark as obsidian, have the hidden fire of celestine, or full of twists like acanthite. Obsidian collects together five novelettes and one novella about the darkness of space travel. Whether it's the brittleness of the human psyche faced with isolation, or the unforgiving harshness of space itself, these stories are reflected in the dark scrying mirror of Obsidian. What will you see when you look deep into its infinite depths?
