That is a great read/translate.
Didn't it read as if translated by a native English speaker? I thought so too. Amazingly adept/scary, with only one really tiny niggle exception for the quoted "Uff" that transliterates better than it translates.
In most cases it didn't loose much of the meaning, but the sentence translated as "It was even nicer that Mats himself, who was lying in the white coffin, had not met these people either." should be translated more like: "Even stranger was that Mats himself ..." or possibly "The only thing more strange was ..." Not fluent in Norwegian so I don't know for sure. But as a Swedish speaker I'm well aware that "rar" ( stem of rarere ) is not translated as nice, as it's one of the more common causes for miscommunication with out western neighbors. In Norwegian "rar" a false cognate with the Swedish "rar", which actually means nice. However, they likely also share common etymological roots, so are cognate and false cognate with each other simultaneously.
