The Year Of the Flood - Margaret Atwood

Adam One, the kindly leader of the God's Gardeners - a religion devoted to the melding of science and religion, the preservation of all species, the tending of the Earth, and the cultivation of bees and organic crops on flat rooftops - has long predicted the Waterless Flood. Now it has occurred, obliterating most human life. Two women have avoided it: the young trapeze-dancer, Ren, locked into the high-end sex club, Scales and Tails; and former SecretBurgers meat-slinger turned Gardener, Toby, barricaded into the luxurious AnooYoo Spa, where many of the treatments are edible. Have others survived?

Oryx and Crake - Margaret Atwood

Pigs might not fly but they are strangely altered. So, for that matter, are wolves and racoons. A man, once named Jimmy, lives in a tree, wrapped in old bedsheets, now calls himself Snowman. The voice of Oryx, the woman he loved, teasingly haunts him. And the green-eyed Children of Crake are, for some reason, his responsibility. 'In Jimmy, Atwood has created a great character: a tragic-comic artist of the future, part buffoon, part Orpheus. An adman who's a sad man; a jealous lover who's in perpetual mourning; a fantasist who can only remember the past.
