This review of Greg Egan’s Oceanic, appearing on the New Scientist website, makes the book sound very tempting. Then again, I’m still recovering from the head explosion induced by the last Egan book I read, Diaspora.
Oceanic is also a short story collection, which I’m disinclined to read. But I’m parking the link here as a note for future consideration.
The review appeared in a special issue of New Scientist, the fiction of now which has a cute little piece of flash fiction from Ken MacLeod, amongst a lot other good nibbles.
Retconned for typos.
