I thought I'd give Jules Verne's 20,000 Leagues Under The Sea a go.(Publication date 1870,Published in English 1872)
Well I've just finished it. Has taken me a while but that's more down to me than the book. It certainly was a slow read and nothing like any movie version I've seen. One might say that not much happens and its not really very 'SF' but on the whole I quite enjoyed the ride!
