Ah, joy of joys - here's a Peter Watts story, set in his Sunflowers universe (he is apparently working on a novel set in it. For Christmas, pretty please? )
This is the same universe in which the Hugo-Award-winning Novelette The Island was set in, and actually follows the same wormhole-building ship/asteroid and its dysfunctional crew and AI. Giants is both highly entertaining, and thought-provoking, and managed to surprise me repeatedly, so good going in my books! The story was originally published in Clarkesworld magazine.
But whilst I'm still waiting to get my mitts on Hotshot, his other story set in that universe (as the novel, I suspect, will take a few Christmases to arrive) - Hotshot has been published in a collection called Reach For Infinity - this here at least allow us to whet our appetite...
