Jitterbug

"On Earth, they depicted justice as blindfolded and impartial, but out here on the frontier, she was red in tooth and claw."

Jupiter and Saturn are gone, and a mysterious force has built a huge habitable sphere from their ashes. When criminals try to lose themselves on this new frontier, bounty hunters like Copernicus Brown and the crew of his sentient ship Jitterbug get paid to hunt them down.

And all the while, something vast and ancient creeps towards them from the depths of space...
