My own suggestions:
- Older novel - The Next Generation, by John Francis Maguire, reviewed by me here. Written in 1870, set in 1891 in a near-future world where there is a railway tunnel between Dover and Calais, privately owned steam-powered balloons are becoming a traffic problem in London's skies, women have had the vote and access to the professions of law and medicine for almost twenty years, Ireland has Home Rule, and Britain has just conquered China. Admittedly it doesn’t do much with those ideas, but it’s an interesting diversion.
- More recent novel: The Dispossessed, by Ursula K. Le Guin. I’m in the middle of rereading it now, so will post more later.
- Non-print media: Doctor Who, of course.
- Older writing: The works of Tolkien. (My own reviews here.)
- Newer writing: The works of Terry Pratchett. (I noted that 19-year-old Pratchett wrote a fan letter to Tolkien in 1967. My other Pratchett thoughts and reviews here.)
- Non-print media: The Expanse.
- Older novel: Animal Farm, by George Orwell. (My review here.)
- Newer writing 1: The Broken Earth trilogy by N.K. Jemisin
- Newer writing 2: the Divine Cities trilogy by Robert Jackson Bennett
- Newer writing 3: the Masquerade trilogy by Seth Dickinson
- Non-print media: Sense8.
- Slightly older book: The Two Faces of Tomorrow, by James P. Hogan
- Slightly newer book: Rainbow’s End, by Vernor Vinge
- Non-prose media: Korean comics.
