Becca Rothfeld's substack is great. I will say, though, I have been having a lot of trouble finding good book writing/ coverage on substack, idk what's going on with the platform

Seconding the untranslated! Also if you like horror, Deep Cuts in a Lovecraftian Vein is generally a great read and a cool place to find under the radar horror (the really deep Lovecraft scholarship is not my thing though)

I recently found out about https://theuntranslated.wordpress.com/, which is the first literary blog I've actually consistently enjoyed the recommendations of. I've previously slept on them as a resource for new books, but am looking to expand now.
