Haunted by memories of children he could not save, Jon Moore becomes so increasingly self-destructive that even his best friend, the hyper-intelligent Predator-Class Assault Vehicle, Lobo, is worried. So when Jon receives both a job offer and a message from a woman from his distant past, he and Lobo leap at the welcome diversions. That the job is illegal is the least of their problems. They're happy to retrieve stolen artifacts from Jon's quarantined home world, and their fee is high even for a job so highly illegal. The forces protecting their targets are formidable, and the assault team that's chasing them is even more dangerous - but Jon and Lobo are used to that. This time, though, the knowledge that they and the others seek could spell doom for Jon.
