When I find an author who writes worlds the way I like 'e I'll read just about everything they put out. I've even read past where I should have stopped. (Hamilton, oh Hamilton you've broken my fangirl heart)
Agreed. She drives me nuts but I'm invested in the characters now.
As for me:
Sean McMullen -- one of my very favorites, he does fantasy and postapocalyptic SF very well, and his writing is consistently humorous too. "Souls in the Great Machine" is my top book of his. I feel his last two were a little subpar, but I'm hoping the next Moonworlds book is better.
Peter David's "New Frontier" -- again, invested in the characters.
Christopher L. Bennett -- all of his Star Trek novels, even "Over a Torrent Sea" which got some pretty poor reviews, are chock-ful of sciencey goodness. His "Lost Era" book on what Picard did between Stargazer and Enterprise is excellent.
Terry Pratchett's "Discworld" -- I really must pick up Unseen Academicals before I go on vacation.
I'm not a huge Neal Stephenson fanboy per se -- I skipped The Baroque Cycle -- but I've read most of his stand-alone novels more than once. "The Big U" is one of my favorites because of the absurdity of the whole thing.
Sherlock Holmes -- I have the complete Holmes treasury, and have read every single Conan Doyle Holmes story and novel.
Ian Fleming -- I borrowed the set of original Bond novels from my brother-in-law-in-law and, while they weren't amazing, they were definitely good reading.
Harry Turtledove's "Worldwar" series -- I'd thought it was only going to be one book, but it turned out to be eight in total -- four Worldwar, three Colonization, and one capstone novel at the end. I liked them all, though I wasn't pleased with the end of the trilogy or the tetralogy because Turtledove's writing is very realistic, and the ends of those series were quite realistic. However, the Turtledove/Richard Dreyfuss collaboration "The Two Georges" is a very fun read once you get past the MC's gary-stu-ness (Dreyfuss, not Turtledove).
Debra Doyle and James Macdonald's "Mageworlds" -- The DMd duo are known to anyone who's attended or applied to Viable Paradise. Right now they're writing historical fiction/fantasy, but Mageworlds is a great Star-Wars-esque tale. There's room for one more book, to tie together the second trilogy, but I think it got kiboshed or something due to the SFF market not having room for it or somesuch. Too bad, too, because I really wanted to know how it ended.
That's everyone I can think of right now.
