Thanks all for sharing your joys and recommendations! I'm collating the list (so far) here for myself/y'all:
Books that were recommended that I already read & loved & recommend myself :)
The Witch King by Martha Wells - after a betrayal, a tired demon helps his angry lesbian witch best friend go on a quest to rescue the witch's stoic paladin wife
Gideon the Ninth / the Locked Tomb series by Tamsyn Muir - engaging puzzlebox story set in a spacefaring necromantic cult, multilayered & twisty worldbuilding, intense moral complexity
This is How You Lose the Time War by Amal El-Mohtar & Max Gladstone - lyrical sapphic love letters between two agents on either side of a violent war across time and space
The Goblin Emperor by Katherine Addison - A young man unexpectedly becomes emperor and befuddles the court with his kindness
The Bartimaeus Trilogy by Jonathan Stroud (though I hear there's a fourth book now!) - GREAT! Engaging, and I wouldn't describe it as "feel good." Sort of like Howl's Moving Castle if it was told from Calcifer's POV and also Howl was an adolescent British wizard who was trying to grow up to be evil in a British empire running on wizardry
Sunshine by Robin McKinley - a baker who specializes in cinnamon rolls escapes a vampire abduction--unheard of--and returns to baking cinnamon rolls. AMAZING first person rambling POV & also always makes me want to run off and start an imaginary bakery
The Lathe of Heaven by Ursula K. Le Guin
The Book Thief by Markus Zusak
Discworld by Terry Pratchett
The Queen’s Thief by Megan Whalen Turner - stunning, engaging, delightful, twisty, read these sixteen million times and find some new double meaning every time. A young thief brags he can steal anything; and he's right.
Ender’s Game and Ender’s Shadow by Orson Scott Card
So You Want to Be a Wizard by Diane Duane - iconic worldbuilding, lengthy ongoing series by a delightful author
