On the Isle of Wight, a colony of survivors wakes to a world plunged into darkness. Before long, the triffids, thought safely out of the way on the mainland, attack.... In John Wyndham’s classic best seller The Day of the Triffids the world has been overwhelmed by killer plants. As the novel ends, Wyndham’s narrator scientist Bill Masen is escaping, with his wife and four-year-old son, to the Isle of Wight where a small colony of survivors is holding out. Simon Clark’s sequel picks up the story 25 years on.
