I had my eye on Brickmakers, but I think you suggested The Wind That Lays Waste to me, if I'm not mistaken. I don't need to have read those two to get to Not a River, right?
My native language is Spanish and literally I was forced to switch halfway through the book to the English version to understand what I was reading. Argentine terminology reaches its peak, to the point that it seemed like a completely different dialect to me. Annie McDermott's task of translating the text into English was titanic. Added to this was the way of delimiting dialogues, the shifts between past, present, and future, the timeless episodes, the overlapping of stories, the non-delimitation of chapters. A challenge that at the end of the book would leave me wondering what the hell did I just read?
