Okay, I don’t read many series in these genres, but here’s what I’ve got:
If you like satirical fantasy, try [name_u]Terry[/name_u] Pratchett’s Discworld novels- a set of books and smaller series all set within the same world. In the same vein for sci-fi, try the Hitchhiker’s Guide to the [name_u]Galaxy[/name_u] series.
For adult fairy tale retelling, try some of [name_m]Gregory[/name_m] [name_u]Maguire[/name_u]’s books- some are individual books and some are connected (like the Wicked series).
If you haven’t given the Lord of the Rings series a try (and related books), I would!
If you’re looked for light magical realism, I would reccomend [name_f]Sarah[/name_f] [name_u]Addison[/name_u] [name_m]Allen[/name_m]’s books. While not a series, the books work pretty well when imagined in the same world.
Again, not a series, but I think [name_f]Octavia[/name_f] [name_m]Butler[/name_m]’s sci-fi books are definitely worth a read. I also enjoyed Nisi Shawl’s Everfair!
If you like really well-crafted fantasy, although it is not a series (again, I’m sorry, but I recommend this book to everyone and it is over 800 pages long), but give [name_f]Susanna[/name_f] [name_u]Clarke[/name_u]’s Jonathan Strange and Mr. Norrell. If you’re interested in a more serial format, there is a faithful and well done TV show version of the book.
If you’re interested in comics as a medium, there are some really great ones!
For contemporary comics, I like Ms. [name_u]Marvel[/name_u], The Runaways, Ta-Nehisi Coates’ Black Panther run, and The [name_u]Vision[/name_u] (2015-2016). These are pretty approachable for new comic readers and for those unfamiliar with [name_u]Marvel[/name_u] at large.
An ongoing web comic that I’m enjoying is Lore [name_m]Olympus[/name_m], a retelling of the myth of [name_f]Persephone[/name_f].
I’m not sure if any of these will be up your alley, but these are some of my favorites!
