Lauren Beukes' 'Slipping' collection is a good mix of bleeding edge urban futuristic short stories, personal essays, and more that's well worth a read, especially if you're a fan of her novels.
The first short story about corporate cyborg athletes was great, seemed to be a Tiptree tribute, but I found the other stories and essays to be pretty forgettable. Plus one awful short story that should have a trigger warning for miscarriage.
