I liked this book. It's not as serious and realist as Abercrobie's writing, not as convoluted as G.R.R. Martin's stories, it's 'adult' without falling into voyeuristic and misogynist drivel or manly-man power fantasies… A good summer reading, with a beautiful map before the story (and even a calendar with special months and weeks)
The worldbuilding is well done, especially when it comes to the use of magic. I was less concerned by the languages invented for the book, but it's of little importance in the logic of the book. Some prominent characters are not as engaging and well rounded as the main, but I guess that's what you get when your narrator is self-absorbed, kinda dishonest (he's a thief, after all) and more interested in this blind cat he found by chance.
