Starling and her grandmother operate a way station in the asteroid belt. For decades, Ganny has had a very successful business, using her way station to sling cargo and passenger ships all over the asteroid belt and to most of the planets as well. But now, technological advances and corporate greed are threatening her livelihood and the continued well-being of her granddaughter. What’s an old lady to do? Digging back into her past, Ganny applies an ancient technique to modern materials. She begins to create a spaceship that will enable her and Starling to survive—and even to prosper. How? By knitting it. All is going well. But once the corporate interests that were plotting to seize her way station realize what she’s up to, they set out to stop her by any means fair or foul. Mostly foul. Her crew is suborned, murder attempts are launched, financial plots are set underway. What’s an old lady to do? Apply a long lifetime’s sagacity and resourcefulness, that’s what. Guided always by her knowledge that revenge is a dish best served old. Written by the Hugo and Nebula award winning author of "The Trouble With Tribbles," The War Against the Chtorr series, "The Man Who Folded Himself," and "The Martian Child."
