Okay, I think I have sufficiently recovered from the crazy awesome to write a review.
Probably the first thing I should say is that I have loved this series for years and years and I have been counting down to this particular book since its publication date was first floated, so those five stars are pretty much a gimme: this book would have had to be actively bad in order to get fewer stars than that. However, even given this bias, I'm quite sure that this book is very, very good.
Although there is the usual attempt to provide context and some recapping, I don't see how anyone could pick up this book to start the series; you really need to read from the beginning. In fact, I went back and re-read book four before starting this one just to be sure I had the proper grounding, and I think it helped a lot. (Also, it drew out my anticipation, but you probably don't care about that.) With that in mind, this is a spoiler flag for the whole series as well as details about book five, so if you haven't read any of it yet, I suggest backtracking!
A lot of the character focus in this book is on Tori and Jame as the lord and lordan of the Knorth; Mullen the forgotten Kendar continues to have a big impact, and Jame especially is dealing with the perils of being an authority figure. Tori's story doesn't really move forward as much as I'd hoped and Kindrie's story was oddly subdued -- so if you're a big Kindrie fan, this is probably somewhat disappointing, since the big reveal goes about how you'd expect but then Kindrie wanders off out of the book again. I'm all about Jame, though, so I didn't mind so much. (I love that Kindrie's first solution to the problem of forgotten names is to write them down, though! Sensible movement away from an oral culture in times of need! It was a jolt to realize that I'd been so immersed in the world myself that that simple solution hadn't occurred to me.)
We actually meet some of the Merikit at last in this book. I'd been a bit worried about the potential wrongness of having someone outside the Merikit culture taking such an important cultural role role in the Merikit religion -- in terms of the cliches in the risk columns, the Merikit are bit Noble Savage, but Jame does not come in as the White Highborn Savior. She saves the village, in fact, by virtue of her in-between gender position. Although gender is something that the Merikit highlight and formalize for her, gender uncertainty and nonconformity have been with Jame since her Talisman days. (The running gag of mistaken identity between Jame and her brother reaches a new height toward the end of this book when Tori wanders around Tentir being constantly mistaken for his sister.) I do admire Gran Cyd's solution to Jame's right-hand-braid problem as well! I admire Gran Cyd quite a bit, actually, despite the clumsy device of having the Noyat ambassador insult her to emphasize his place as a bad guy. Part of that is that she took the Earth Mother's word that Jame was the Earth Mother's Favorite for the year and didn't make her prove herself all over again; that's real faith for you.
Speaking of faith, Jame seems well settled on being the forefront of the Tyr-ridan these days. Perhaps some of that weapons training is paying off? Although she's moving awfully fast toward physical violence, and I'm still not sure what to make of the scene with Vant (especially since its actual occurrence from Jame's point-of-view was much calmer than Jame's berserker flares usually are, for all that her reaction afterward (and Harn and Sheth's comfort) are highly suitable. (Can I mention, tangentially, how much I really admire Sheth? He's a fantastic role model for Jame, Caineron and all.) I also really like Trishien's role in this and feel stunningly sorry for her. The play of politics is getting really complex here, with the Ardeth sinking into degeneracy and madness and the Caineron and Randir breaking free and rising. I'm really starting to need a diagram of alliances, though!
Which leads me to the awesome glass map that Marc is rebuilding. I really love the details on this. There were a lot of really nice little touches in this book, like the Body-Becomes-Water exercises and the purring cocooned wyrm, and really creepy ones, like the sargent who carved her son's name in her arm or Harn helping his father with the white knife.
Looking back over it, this isn't a book in which a great deal of plot happens; almost everything which goes on is in the character development and the behind-the-scenes shifting alliances. I really enjoy this, but partly I feel free to revel in this little breather while something big is clearly building with Urakarn and poor Graykin. ...When's the next book already?
