Pudgy Penguin Perusals: The Day of the Flood by Margaret Atwood
From Amazon description: "The times and species have been changing at a rapid rate, and the social compact is wearing as thin as environmental stability. Adam One, the kindly leader of the God's Gardeners--a religion devoted to the melding of science and religion, as well as the preservation of all plant and animal life--has long predicted a natural disaster that will alter Earth as we know it. Now it has occurred, obliterating most human life. Two women have survived: Ren, a young trapeze dancer locked inside the high-end sex club Scales and Tails, and Toby, a God's Gardener barricaded inside a luxurious spa where many of the treatments are edible.
