I'm going to have to think hard how to come up with something different to Ammonite132's comment; I just bought this book on a whim whilst in town. Started reading it at 5:30pm, finished at 8:15pm - I was absolutely enthralled, totally blown away, and am now enthusing about the story more than any other that I can remember.
It's a science fiction story, but unlike most other stories in the genre it only uses the SF element as a core part of the idea, and then weaves the story around the lives and experiences of the characters over the years that follow.
It's touching and thought-provoking, and - as with all the good things in life - focusses on sitting around a fire in the local pub, chatting to close friends!
I'll be proselytising about this one to my wife, my parents, my colleagues; anyone who will listen. I'll probably have to buy myself another copy to lend out...
I'd be interested to see if Eric Brown can come up with other stories of the subsequent exploits in the wider universe alluded to within this novel, but even if he doesn't, I'll be certain to check out all of his other stuff.
