Two science fiction stories by Nebula-award-winning author Linda Nagata: In the nanotech-drenched future of "Nahiku West" anything is possible, but not everything is allowed. Police officer Zeke Choy is charged with enforcing molecular law--but his first task is to determine if a crime has taken place. "Nahiku West" is a Nanotech Succession story, set in the same world as the award-winning novel The Bohr Maker. (~9,000 words) In “Nightside On Callisto” four aging explorers accept a hazardous mission to Jupiter’s airless moon, a place of unimaginable cold and lethal radiation--but Callisto proves less dangerous than the enemy they brought with them.
