Seven brilliant short stories by the award-winning author of Ringworld. Inconstant Moon - a moon so bright could only mean one thing. The sun had gone nova. Death by Ecstasy - Belters didn't get addicted to current stimulation, so why did the spacer die with electrodes in his brain? Bordered in Black - the continent had a thin black border all the way around. The things that made it drove a space explorer raving mad. These are three of the superb stories in this collection by Larry Niven.
