After creating the Reader's Guide to Wuthering Heights, I looked around for another book and turned to my favourite science fiction novel, John Wyndham's The Day of the Triffids. The site was started before Wuthering Heights had been completed and was also published in 2007.
If you've never read The Day of the Triffids, it is a fine example of apocalyptic fiction, describing the world after an apparent comet blinds the vast majority of the population. The survivors also have to deal with triffids – large movable plants with a deadly sting. But the story is more than a battle against mutant monsters, it's more about what sort of society do we build after a disaster and how we cope.
