THE BIG BURN LASTED FOR THE BETTER PART OF AN HOUR. BY THE end of it, they’d consumed so much propellant and made Endurance so light that acceleration made the blood fall out of their heads and pool in their feet. Ivy piloted the ship lying flat on her back, lest she lose consciousness. The journey was punctuated by a few terrific bangs, and those who could stand to watch Endurance ’s status readouts could observe various modules turning yellow, then red, then black as they succumbed to damage. Dinah watched through the eyes of several cameras as a ten-mile-long piece of the moon tumbled past them, overtaking them and zooming by just a few hundred meters to their starboard side. Nor was that the last such encounter; but with Doob acting as her wing man, calling out the biggest threats, and with Dinah making such use as she could of Parambulator, Ivy was able to steer them clear of the big stuff.
