The Year of the Flood - Margaret Atwood

A novel set in a near future, where the world is ruled by the corporations and their security corps - CorpSeCorps.  There are dissidents called God's Gardeners who live as 'green' a life as possible, and while they have no answers, they do ask a few questions.  Then we have the pleeblands - the equivalent of our 'sink estates'.

This is the same place and time as 'Oryx and Crake' - but from a different point of view.  Most of humanity is wiped out by a plague, and The Year of the Flood takes place just before and after this event.
