The only 'real' fantasy book I've read recently is Stardust by Niel Gaiman, and I'd definitely recommend it. It is simultaneously easy to read and very evocative of it's magical imagery. Reading it reminded me of being a child of maybe 9 and just being completely immersed in a fantastical world. It's sort of an 'isekai' story.
Also, though maybe not what you meant, I'd highly recommend houseki no kuni aka Land of the Lustrous. It's an ongoing manga about a group of a-mortal and genderless gem people on future earth who try to ward off attacks from deity-like lunarians. The story follows the main character, Phosphophyllite (just look at my name, you can tell I like this manga) who is weak and unsuited to battle or any other useful task.
