Title: Down to a Sunless Sea
Description: Review:This book was published in 1981 so is a little dated but well worth reading and very frightening.

A post-apocalyptic novel about a planeload of people during and after a short nuclear war, set in a near-future world where the USA is critically short of oil. The title of the book is taken from a line of the poem Kubla Khan by Samuel Taylor Coleridge.
