"Klara And The Sun" by Kazuo Ishiguro
Just finished it the other day, and I gotta say - the author credibly serves first-person narration from the perspective of an android AI character!
I wouldn't call this HARD scifi, because the tech of the world is not really a part of the book's focus - in fact, in a very VERY interesting twist, there's more of an element of superstition in play: Klara is fundamentally *solar powered* and consequentially her relationship with the sun (as the title suggests) is easy to recognize as just, like, normal human superstition, the way humans in the past worshiped the big fireball in the sky that brought warmth and light into their lives!
So while she's an artifical intelligence, but she's not an alien intelligence, or even a recognizeably robotic one - she thinks and feels and reasons like a human, albeit one whose mind is, as ours is, closely coupled to the mechanics of her own body.
Sometimes she describes her perception of her surroundings as being separated into 'boxes' - as if she's aware, on some level, of her own subconscious process of 'sampling' the input of her various sensors - sometimes her awareness can be filled with multiple 'boxes,' splitting her own finite attention between all the different sensory inputs, tracking many different things around her - other times, particularly during moments of great importance when her attention is focused on a single subject, each 'box' samples a subtly different aspect of her view (e.g. 16 different elements that make up a human facial expression) It's a lovely storytelling device, and it all comes from Klara, in her own words!
I went into this book blind (my preferred method for approaching media!) and - I was kind of blown away!
Very much recommend if you'd like to read a bit of near-future speculative fiction, with a focus on telling a very recognizably human story through the lens of a non-human intelligence!
