Book #39 of the 50 Book Challenge...

Greybeard by Brian Aldiss

From Goodreads.com
The sombre story of a group of people in their fifties who face the fact that there is no younger generation coming to replace them; instead nature is rushing back to obliterate the disaster they have brought on themselves.

My take:

2 out of 5 stars. The story never seemed to go anywhere. I just didn't really enjoy the book. Considered classic science fiction but it lost a lot of that feeling of complete hopelessness that most books from the 1960's seemed to have.
