From the back of the book:
When the gangs tear up the freeway... choose a side. Fight. Survive.
Two great nations that were destined to never find peace disappeared overnight. one is not an irradiated hot-zone where nothing survives. The other a sparsely populated wasteland that has plummeted into anarchy and chaos. Water, gas, and food are the only currencies that matter on a continent ruled by bullets, balls, and bloodshed.
