Any good books similar to the style and themes of Aldous Huxley's novels?

The Handmaid’s Tale by Margaret Atwood is a novel of female dystopia.
Also try Never Let Me Go by Kazuo Ishigutro

The novels by Evelyn Waugh are in a similar vein.

Also, William Golding’s Lord of the Flies.

We by Yevgeny Zamyatin

And in a slightly different, but still dystopian vein, Stranger in a Strange Land by Robert Heinlein.

I read Brave New World around the same time I read Dune by Frank Herbert. Liked them both a whole lot. Don’t know if that helps.

Try “A Canticle for Liebowitz”

thank you guys! I’ll check those out. :)

Not challenging but favorites:
The Girl, the Gold Watch, and Everything, a very unusual novel for John D. MacHonald
The Door Into Summer, Robert Heinlein

Both about second chances [who doesn’t want them?]

and try
A Clockwork Orange (1962) is a dystopian novel by Anthony Burgess even if you saw the movie

and William Golding’s Pincher Martin and Inheritors

The “I Robot” series by Isaac Asimov.
“2001: A Space Odyssey” by Arthur C. Clarke
“The Yiddish Policemen’s Union” by Michael Chabon
