Return to the Whorl

I had to give it up; I loved the first 2 books in the trilogy (amazing use of language, great character and story development, excellent dialogues, some complex questions on humanity and so on), but this is unreadable: not only is it uninteresting as the story does not really develop any more, rather goes back in a boring way, but it is really unreadable for a non-native in English. Just a quote as an example: ”Gae ter t'other h'end, though, h'if there's nae help fer h'it. Yer need nae come wi' me, h'if yer finds yer h'own short a' there”.
Gave up after 100 pages...
