Palimpsest by Charles Stross

Agent Pierce murdered his own grandfather to join Stasis, the covert organization which works outside of time to reseed the Earth with humans every time they’re about to make themselves extinct… It’s easy to see why Palimpsest won the Hugo Award for best novella in 2010… You’d be tempted to think that time-travel, with its accompanying paradoxes, is a well-worn theme, and Palimpsest does re-visit some of the age-old questions, but it’s got some fresh and fascinating questions to ask, too… In his afterword, Charles Stross says “Palimpsest wanted to be a novel. It really, really wanted to be a novel. Maybe it will be, someday.” I agree: Palimpsest wants to be a novel. It needs to be a novel. I want it to be a novel. This superb story deserves much more space and time (so to speak). Read the rest.
