Crichton Kicks
After months alone on a dying Leviathan named Elac with nothing to do except put down his wormhole knowledge, Crichton has gone almost completely insane. He's only broken from this state by the arrival of Leviathan "expert" Sikozu, the band of pirates pursuing her, and some old friends in trouble.
