I just finished this one so it might just be fresh in my memory, but I really enjoyed Kiril Yeskov's "The Last Ringbearer". It's a sequel/retelling of Tolkien's "Lord of the Rings" written from the Mordorian perspective and based on the premise that LOTR is "a history written by the victors".
It has a completely different feel than Tolkien's writing, and sort of stuffs something resembling Cold War politics into Middle Earth. It's obsurd, but somehow makes perfect sense.
I originally saw it recommended on hn, so thank you whoever you were!
You might enjoy Jacqueline Carey's duology The Sundering. It's sort of LoTR told from the side of the "bad" guys, though it's set in its own original world, and the story isn't an actual retelling of LoTR.
I haven't read it, though it's on my list. It wasn't commercially published in English out of concern for running afoul of Tolkien's estate. Instead, it's available for free as an ebook:. https://ymarkov.livejournal.com/280578.html
