Can you recommend a book for me please?

I’ve basically been ordered to pick up any fiction book and read, after a friend discovered I’ve not read anything but non-fiction for a decade.

The ones I’ve enjoyed in the past have been short, fantastical or sci-fi (think Aldous Huxley, Ian McEwan), but crucially with amazing first person descriptive prose - the kind where you’re immersed in the writing so much you’re almost there with the character.

I liked sci-fi as the world’s constraints weren’t always predictable. Hope that makes sense.

Any recommendations?

Edit: I’m going to up the ante and, as a way of motivating myself to get off my arse and actually read a proper story, promise to choose a book from the top comment, after, let’s say arbitrarily, Friday 2200 GMT.

Edit deux: Wow ok I don’t think I’ve ever had this many responses to anything I’ve posted before. You’ve given me what looks like a whole year of interesting suggestions, and importantly, good commentary around them. I’m honouring my promise to buy the top thing in just under 4 hours.
