Being a long time fan of Greg Egan's since his fantastic book Diaspora, I had grown a little dissatisfied with his more recent efforts up until Incandescent and now the brilliant collection Oceanic.
I would have to call this one of the best collections of short stories I've ever read. Thoroughly enjoyable, the stories collected within dive deep into hard sci fi while never losing the reader. Adventurous, while still making the reader think, yet always being firmly based in humanity and character.
Reading this collection is a pivotal moment. Any sci fi that deals with the expansion of humanity and doesn't deal with it in the way Egan does now seems old-fashioned and plain silly and evokes thoughts of 50s futurism and duck-and-cover absurdity. Greg Egans ideas are brilliantly simple to the point that once revealed to the reader it's hard to believe it isn't exactly what will happen.
I can't recommend this collection enough.
