I started to read Malazan Book of the Fallen[0], a very dark and heavy fantasy series. I started in English, then switched to my native language, now to have maximum fun from it (as I like it a lot), I read one book in native and then reread in English.
What I've noticed is that reading in my native language makes me feel much more connected to characters, I see the whole relations between persons more vividly and intensively. Then rereading in English, the same characters (which I already know and like!) feels much more distant and abstract.
But :)
All the fantasy scenes plays much better in my head in English than in my language. For some reasons sentences like "blood dripping from sword", "screams of souls", "massive", "darkness", "spread his wings" etc instantly trigger the feeling of magnificent and out-of-this-world scale of experiences. Even though translation is top-notch, for those parts I prefer the English version.
Very interesting experience.
