I could not get through Banks’ “Feersum Endjinn” for this sole reason. English isn't my first language, though I’m fluent in it and read lots of hard sci-fi in it. But half a book using English “spelling rules” applied haphazardly just to make a minor point about one character was well beyond my capacity. I quoted “spelling rules” on purpose because let’s be honest, English doesn’t really have any.

You couldn’t translate that novel to Italian or Finnish, or any language with proper phonetical spelling.

As a native speaker I found it pretty easy to read.
