As The Dispossessed starts with a wall, Annihilation starts with a tower. And as LeGuin’s wall round a spaceport both closes the planet off from the rest of the universe, and encloses the universe, depending on how you look at it; so VanderMeer’s tower has its topological oddity. It starts at ground level and goes down, into the ground underneath it, rather than rising into the air.

Or so the Biologist sees it, But this is Area X, and things are rarely as they seem.

The Biologist is the first person narrator. Accompanied by three other women — the Psychologist, the Anthropologist, and the Surveyor — they are the latest in a series of groups sent in to investigate the mysterious zone.

Almost everything is unexplained in this book. It is incredibly compelling, gripping, even, but everything remains unexplained, the ending is open. Yet while there are three more books in the series, I feel it’s such a perfect little nugget, beautifully crafted, that to read on would almost spoil it.

I suspect that’s not true, though. We are in safe hands with VanderMeer, so I expect the continuation will be sound. I remember my friend Simon having a similar response when he read Hyperion. Its perfectly-crafted open ending seemed to him like it didn’t need a sequel. But of course The Fall of Hyperion was magnificent, and so were the two Endymion followups.

Anyway, this is great, but you probably already knew that, what with winning awards and being ten years old.
