What if bacteria turned all the gasoline in Los Angeles into vinegar? Carmageddon doesn't begin to describe it; PETROPLAGUE does. UCLA graduate student Christina Gonzalez wanted to use biotechnology to free America from its dependence on Middle Eastern oil. Instead, an act of eco-terrorism unleashes her genetically-modified bacteria into the fuel supply of Los Angeles, making petroleum useless. With the city paralyzed and slipping toward anarchy, Christina must find a way to rein in the microscopic monster she created. But not everyone wants to cure the petroplague--and some will do whatever it takes to spread it. From the La Brea Tar Pits to university laboratories to the wilds of the Angeles National Forest, Christina and her cousin River struggle against enemies seen and unseen to stop the infection before it is too late. Set in the mountain-ringed Los Angeles basin, this terrifyingly plausible science thriller about good intentions, unexpected consequences, Peak Oil, climate change, experimental biofuels, and the astonishing power of microorganisms will give you pause every time you fill up your car.
