Losers in Space - John Barnes

It is the year 2129 . . . and fame is all that matters

Susan and her friends are celebutantes. Their lives are powered by media awareness, fed by engineered meals, and underscored by cynicism. Everyone has a rating; the more viewers who ID you, the better. So Susan and her almost-boyfriend Derlock cook up a surefire plan: the nine of them will visit a Mars-bound spaceship and stow away. Their survival will be a media sensation, boosting their ratings across the globe. There's only one problem: Derlock is a sociopath. Breakneck narrative, pointed cultural commentary, warm heart, accurate science, a kickass heroine, and a ticking clock . . . who could ask for more?
