I think that the more alien and strange a world or situation is, the more concise you have to be if you want the reader to follow you. It depends on what effect you're looking for.

I'm just being honest about the fact that a second language won't resonate with you like the first does.

All my stories and worlds spring from the basic principle of being a slave to the premise, to follow the consequences wherever they may lead without taking any easy or comfortable ways out.

I don't consider genre while writing.

Some stories I write in Swedish, some in English. Short stories I've almost exclusively written in English lately, mostly because there's such a small market for them in Sweden and it doesn't really pay either. So, the translation goes both ways. What also factors in is that I have a different voice in English, which means that a straight translation wouldn't be the same as if I'd written it in English originally.

If you want the reader to accept the premise as a given, then being specific is vital. This is what I'm after; I want the reader to accept the setting and the mindset of the characters, so we can get on with the story.

My early stories revolved around reality and faith. I wrote a series of stories about the darker aspects of Christian myth: a woman who hides in the attic and watches the Apocalypse, a cult whose members preserve themselves in huge formalin tubs waiting for the Second Coming, and so on.
