Labyrinth

Ever woken up with that 'Where am I' feeling?
Yeah, most people have.
Was the place /where/ you woke up a death trap (complete with man-eating monsters, lava, and all sorts of abnormal crap) that you'd been chosen to be shoved in?
Probably not.
Except that whole death trap scenario's exactly what happens to Marty Collins, a sixteen-year-old girl who finds out her name was drawn for the infamous Labyrinth. The Labyrinth being a giant maze underneath the United States, created for the sole purpose of population control.
Here, it's kill or be killed, save for a few strange tribes and alliances. Marty's /not/ clueless... But she isn't exactly sure what to do about being stuck in the maze, either. That is, until she meets a few companions that further complicate every freaking aspect of her new life, turning her world completely upside-down.
Well, there's no such thing as a pleasure in a death trap, right?
