Weirdly, I had never heard of Joe Haldeman until son no.2 mentioned him. And yet he's a Hugo and Nebula Award winner and apparently has written classics. Then I saw that I had Mindbridge on my shelf, no doubt passed on to me by my father, so I picked it up rather curiously.
   It's a slim, slightly old-fashioned Futura publication, and truth to tell I wasn't expexting much from it. But I was wrong. It's rather a clever vision of humans meets aliens, with some text layouts that must have looked special back in the day. It's very much plot-driven. Yes, there's some attempt to bring out some character traits, but it's a bit thin compared to today's SF. 
   Still, I enjoyed it. Goodness knows where you might see this book (published 1977) but if you do see it, you won't go far wrong if you buy it.
