Combustion (Corey Purchase and Judd Bell) Unabridged edition

Los Angeles. Traffic clogs the streets. Smog chokes the city. And Zac Bunsen is going to burn it all down. On a ruthless quest to save the planet, Bunsen releases the Swarm, an airborne nanotech virus that targets combustion engines and detonates their fuel supply. It is spectacularly, appallingly successful. Terror and chaos reign as the City of Angels explodes. Every vehicle is now a deadly bomb and every freeway a war zone littered with bodies and twisted wrecks. NASA astronaut Judd Bell and his best mate, Aussie chopper pilot Corey Purchase, must navigate the burning city in a desperate mission to stop Bunsen before he can execute the last phase of his horrific plan and send mankind back to the Stone Age.
