All Against All — Nathan Allen

One rule. One winner. One hundred million dollars.

A group of random strangers are invited to take part in a mysterious lottery with an intriguing premise. Twenty-seven accept the offer.

 
But what begins as an unusual social experiment quickly descends into something much more sinister. The contestants receive more than they bargained for, and the dark side of human nature reveals itself.  

As the lottery spirals into a life-and-death struggle for survival, Alice Kato is left searching for answers. How far are ordinary people willing to go to win this extraordinary amount of money? Is there anyone she can trust? Is there any way out?  

And just who exactly is pulling all the strings?  

Everyone has their price. Most just don't know what it is yet.
