Writing a sequel to The Day of the Triffids, John Wyndham's 1951 science fiction classic, is something most authors couldn't even attempt. It's not enough to pastiche Wyndham's style; that would just leave you with a quaint literary curiosity. The sequel needs to match the inventiveness and blistering shock value of the original but in a modern idiom. Think the retooled Battlestar Galactica or the way J J Abrams created a new take on 1960s-era Star Trek.
Perhaps the only writer who could hope to do justice to such an undertaking is John Whitbourn, one of England's greatest living practitioners of fantasy and science fiction. In The Age of the Triffids, he leaps ahead to twenty-five years after the time of the first novel. Bill Masen's community on the Isle of Wight has grown and on the surface appears to be thriving, but with fields of triffids covering most of the mainland and spores ever drifting on the wind, there are threats from outside and perhaps an even greater danger posed by the concomitant social fault lines between the pre- and post-apocalyptic generations.
"Resist the temptation to hide. Otherwise you’re trapped and you'll never get out. Triffids have all the time in the world. Sooner or later, hunger or thirst drive you into the open. They will be waiting."For copyright reasons The Age of the Triffids is only on sale in Canada and New Zealand. But if you can't wait two decades for the rest of the world to catch up, why not see if a Canadian friend (or bookshop) will send you a copy?
I'm strenuously opposed to book series that go on and on long after they've run out of steam, but what would be your choice for another classic standalone SF or fantasy novel that's crying out for just one good sequel?
