Sunfall by Jim Al-Khalili ?

[TheFirstOHN]

I love science fiction and enjoy the apocalyptic genre, but I wouldn't normally spend as much as £9.99 on a kindle book.

Has anyone read this? If so, is it any good?

I haven't, sorry. But I love him, so will have to now. (It is the Professor guy, right?)

Yes, him.
I think I'm going to wait for reviews / recommendations first.
