The Year of the Flood by Margaret Atwod

You may have guessed it, this book is the sequel to Oryx and Crake, the 2nd in the Maddaddam trilogy. Like many good trilogies, this one stars a different set of characters and focuses on a religious cult that has predicted the events to come in Oryx and Crake (the end of humanity). The Year of the Flood gives a stronger glimpse of what life is like in this theoretical future for those who are both female and less fortunate than Jimmy and Crake. Needless to say, it's juicy and makes you wonder if the prophet was privy to the nature and source of the pending flood.
