I found this in a charity shop and bought it because the premise seemed an interesting one, given the current geopolitical and climate landscape.
I am rather enjoying it so far. It is not my normal type of book so it is taking a bit longer to read it than I would like, but it’s a definite finisher.
Edit: having finished it I can say that the premise is brilliant and very topical. The book starts slow and ends suddenly but the meaty bits were really interesting. I wish the author had written more about human behaviour inside the ‘terrarium’
