I’ve long been a fan of Australian science fiction author Greg Egan, whose work is pretty much guaranteed to do your head in. (I mean that in the nicest possible way.) His writing has always included radical approaches to gender and sexuality – but none of his previous novels has addressed sexual politics or a liberatory struggle for reproductive autonomy as directly as those in the Orthogonal series. The results of his latest efforts are characteristically fascinating. I’ve reviewed the first two books in the trilogy for the F Word.
