Strange things are afoot in South London. First it rains non-stop for weeks. Then buildings start to collapse of their own accord. And then odd blue flowers begin to grow amidst the debris. Everyone starts calling them Bluchers.
Ade only half notices this happening, despite having a splendid view of the city from the balcony of the tower block where he lives. His mum recently suffered a brutal attack near to where she worked and has become increasingly more reclusive, to the extent where Ade has to go out and buy food for them both. But he can’t ignore what’s going on when everyone else in the block decides to leave. Ade’s mum won’t leave her bed, though, so Ade stays behind with her. Except, as he soon discovers, he’s not the only one left behind.
There are all sorts of things going on here. Ade’s life hasn’t really changed all that much. He was just as lonely before the Bluchers appeared. His experience of this apocalypse comes down to missing going to school and not being able to spend time with his one friend, Gaia. His home is a place where hundreds of people are all living on top of each other, but his world is one of alienation and isolation. It takes calamity to change that.
Ade is the sort of innocent, sensitive and kind character that makes for an instantly familiar and likeable narrator, his only flaw his slight naivety. Whilst he’s never passive, it’s only towards the end of the book that his true strength emerges.
Any story about killer plants is obviously going to draw comparisons to John Wyndham’s Day of the Triffids. Even though the Bluchers aren’t walking around the place, that doesn’t make them any less menacing. Their level of sentience is left rather vague, which doesn’t help. You’d like to believe they are actually quite innocuous, only killing us all by accident. And perhaps that’s they way they like it.
