Doubt

"Within an abandoned old building, the popular mobile-phone game Rabbit Doubt-in which players must try to discover the wolf in rabbit's clothing or pay the bloody price-has become a grotesque reality for a group of online friends. As the bones pile up, the survivors begin to question one another, and the seeds of suspicion take root. Who to trust? Who to doubt? With the wolf on the prowl, culling the herd, will any of the unfortunate souls caught up in this twisted game of murder be there to bear witness when the mastermind is finally unmasked?" -- p.
