Plague Year - Jeff Carlson

"They ate Jorgensen first."

Plague Year begins with a bang and the roller coaster of events doesn't stop until you run out of pages and start looking for book two, Plague War. Nanotech designed with the hope of creating immortality and ending cancer has overrun the world, destroying all warm blooded life below 10 000 feet. The few survivors are slowly starving to death and fighting over the few resources still available.

Focusing on two groups - one in the Californian mountains, one in the heart of the remains of a corrupt government, the novel shows how in times of crisis the best and worst of human nature survive.

And if you haven't seen the book trailor, take a look. It's one of the best out there.
