I am into linguistics sci-fi, and it was in search of more of it that I read this book. Or, at least, tried to read it: I gave up about 60% in, and it didn’t work for me at all. First Contact, dodgy language experiments on kids, just as dodgy writing, some rainforest activism, plus no women (released in 1973, and I know for a fact that there were women on Earth even back then), โฆ there was nothing to keep me going.
I'm currently behind on reviews, so don't be surprised if the recent reviews are a bit sparse.
