Read a book years ago which I'd like to find..as much as I recall is the sea disappeared and a man,the main character, walks from one of the Channel Islands to England..not much to go on but if anyone has any ideas??
File Cutter, when I read the question I was thinking it could be a John Christopher book although I havent read that particular one. I read the Death of Grass when I was 14 and it scared the pants off me. I re-read it about 2 years ago and while I appreciate that it was written in the 50's, it still holds true today and still scared the pants of me!
I've read loads of post apocalyptic fiction books - if you enjoyed
"the death of grass" you will probably also like "famine" by Graham Masterton - similar premise but by a horror writer.
