Currently reading The Windup Girl by Paolo Bacigalupi.
In the novel plagues, sea level rise and the depletion of carbon fuel sources have altered the face of the planet. Biotech megacorps seek to hack together genetic information from what few crops remain in order build foods resistant to the new diseases and monopolize the calorie market. It’s a sort of agricultural cyberpunk. Like all good cyberpunk, it takes place in a familiar feeling future that may not be too far distant.
