A young man, part of a scientific mission that is going to change an alien habitat to suit human habitation, finds out something whilst surfing, and has a moral dilemma to face, whilst recovering from a wipeout that requires fairly major surgical intervention. On a blind reading test though I’d have plumped for the story being from Analog rather than F&SF. But then again, as I have the odd moan about there not being enough SF in F&SF, that would be a bit churlish of me.
