Has anybody read this book? It sounds so sick and awesome. I'm thinking about buying it.

It's about a horrific walking contest where 100 contestants volunteer to enter. There isn't a finish line. It's a circuit. There isn't a number of laps. Just you, 99 contestants and the long long path. However, this isn't any ordainary walking contest. If your speed drops below 4 miles per hour, your removed - from life via bullet in the head. The winner; the last man standing.

Imagine that! No rests, no stops, no nothing. Well, your issued food and water throughout the day by soldiers. But, oh my god! That would be so sick! So, has anybody read this? Any good?
