Noticed it in my books on the Kindle app (I’d preordered it and definitely missed any email about it), and basically inhaled it last night. Well done and surprising, but I did feel let down by how little of all my favorites were in there. Most of the story was about the journey of Kamet with Costis, and I like Costis, but not quite enough for the end to remove that disappointment.
That said, it was a good story, a wonderful character and friendship arc, and the end did bring a point to it all and a great step along the overall story arc of the series. The post-denouement pieces were priceless every one. A nice installment with lots of little rewards.
