I’d highly recommend the following. Apologies if you’ve already read them, etc.
Never let me go, by Kazuo Ishiguro. Modern classic. The movie is also excellent. One of the best adaptations of a novel I’ve ever seen.
We, by Yevgeny Zamyatin. Among the first dystopian novels. Came out in English in the early 1920s. Really good.
Kallocain, by Karin Boye. Read it back in the early 1990s, so have forgotten most of it. Just remember loving the story and the writing.
The Handmaid’s Tale, and its recent sequel, The Testaments, by Margaret Atwood. Classics, both.
Station Eleven, by Emily St. John Mandel. I liked the sequel too, Sea of Tranquility, but not as much. Have not seen the series of the former yet.
Zed, by Joanna Kavenna. One of my favorite novels of the past few years. A great read. Wish they’d do a series about it.

Will add some more, later, when I recovered a bit from last night’s game.
