I just finished Earth Abides by George R. Stewart. It had been on my 'to read' list for awhile after seeing it discussed on Hubski various times and it's probably the best book I've read this year. I love how it used its premise to explore civilisation and ecology to the extent that it did. It had much more gravity that I was expecting.
I'm now reading Slaughterhouse Five by Kurt Vonnegut, a book I've been meaning to get around to for even longer. It was on sale for 99p on the Kindle store so I felt obliged. I've only read the first chapter so far which seemed to mostly be a meandering preamble, so I'm looking forward to getting into the actual meat of it.
