Read (partly re-read due to anthologies) Greg Egan's
Luminous. All but the last story are 1st-person narratives set on Earth in the relatively near future and some are even in present tense. Definitely not how I'd ask a collection to be constructed in the abstract.
My favorites:
"Reasons to Be Cheerful" is a brilliant story of a boy who has brain cancer, the radical treatments he undergoes to try to beat it, and the radical side effects. It deals with some fascinating questions of neurobiology, pleasure/pain, choice, identity, etc. Indeed, these are central features of several of the stories.
"Chaff" is a story about a sort of artificial jungle, the drug dealers who live there (and "drug dealer" doesn't begin to cover it) and the murderous spook who goes in. This directly quotes "The Heart of Darkness" regarding principles being chaff in the wind before things like hunger and goes beyond that.
"Transition Dreams" is a truly creepy whacked out tale of what it might be like to have your brain translated into software, if that's even what goes on in the story. Buckle up, 'cuz it's an intense ride.
The last story takes us out to explore a black hole (though we're actually exploring the societies of our AI descendents). As "Transition Dreams" mentions "Gleisner robots" directly and those occur elsewhere, this story also shares background ("fleshers" and polises and so on) with some of his other works like
Permutation City,
Diaspora, and
Schild's Ladder, IIRC, though none of this forms an actual series AFAICT. There's some really harsh slams at magical thinking, historical truth, and "poetry" which includes a truly brilliant analogy regarding statues but I'm not sure how seriously Egan intended this to represent a whole view.
Less great but still very good, the title story deals with ideas of mathematics only being true via empirically being made true and how competing mutually incompatible mathematics might be misused by some forces and how our protagonists try to avoid this. And "Cocoon", is also pretty good, being about a gay cop in a privatized police force being brought in to handle a crime that ends up bringing his identities and loyalties (and humanity's behaviors and so on) into question.
Dropping another level, "Silver Fire" was maybe great, being about social decay, superstition, and a truly horrific disease but was a little too cruel and vicious without enough catharsis only to make a point that, while important, should be fairly self-evident and... I dunno - it just wasn't worth it for me.
"Mister Volition" and "Mitochondrial Eve" were both okay but actually flawed. The first seemed to me to be an unsatisfactory scenario using a miscast psychopathic protagonist to illustrate some ideas about the little dude in the "I" who may or may not be supposed to be pulling the levers. Nifty idea, but I dunno about the execution. And the latter is kind of as pig-headed in its own preachiness regarding human tribalism as the "bad guys" are supposed to be.
But the only one I didn't like at all (except that parts of it were still really well written and it held my interest in the course of the reading) was "Our Lady of Chernobyl" but that may be simply because either I didn't understand it at all or I disagreed with how he chose to resolve it. It deals with a private eye being sent to track down a missing religious icon after the courier transporting it is murdered.
Still, 4 superior stories, 2 lesser ones that still shouldn't be missed, a trio of fair filler and one that could have been left out (yet was the title story of a small press collection and was still readable). A highly recommended collection from one of the very best.
(But somebody needs to tell Egan that his American characters would never do anything for a "fortnight" (two weeks) or use a "torch" (flashlight) and few, if any, would be "disorientated" (disoriented) and so on. )
