An AI overseer and a human crew arrive on a distant planet to salvage an ancient UN starship. The overseer is unhappy. The crew, well, they're certainly no A-team. Not even a C-team on the best of days. And worse? Urmahon Beta, the planet, is at the ass-end of nowhere. Everybody expects this to be a long, ugly, and thankless job. Then it all goes disastrously wrong. What they thought was an uninhabited backwater turns out to be anything but empty.

Mattie and Brewster are normal, typical 16-year-old twins who live with their normal, boring parents: Martin and Gwen Banks. Normal and boring, that is, until the day their father's best friend shows up at their house - dressed in what appears to be a bathrobe. The next thing Mattie and Brewster know, their parents are frozen like human statues in their living room, the guy in the bathrobe has vanished, and they need to find answers - fast.
