The books I love most in the world to read are epic/historical fantasy novels that feature cool heroines doing cool stuff. This book is just what I ordered.
One of the things I enjoy most about this series (so far, of course) is the rich diversity among the female characters. They range from the good (Isabeau) to the evil (Maya, Margrit), from the aged (Meghan) to the very young (the delightful Finn, who, while everyone else is preparing to charge to her rescue, calmly frees herself from danger), and from the human to the nonhuman (Lilanthe, Cloudshadow). I have my favorites among them. I've noticed that some reviewers don't care much for Isabeau, and it's true she doesn't get many opportunities to be her most powerful self, but I value her kind heart, which goes out to baby Bronwen even though she's the child of her bitterest enemy. I also love fierce, fearless Meghan; the marvelous Judi Dench is always in my mind's eye when I read about her. I want to see Iseult do some real fighting, but I have hope that will come later. I didn't care much at all for the male lead, Lachlan, but then I don't think I'm supposed to. It's rather interesting to me that despite being the rightful heir to the throne, ostensibly the "hero," and despite his supposed romantic devotion to Iseult (though he shows precious little tenderness even to her), Lachlan isn't that much more sympathetic than his evil rival Maya. Our "hero" even threatens the life of an innocent infant! This moves the book out of a simple "good vs. evil" struggle and into more complex territory.
I do have a couple of nits to pick.
First, it troubles me that the vicious, bigoted Tirsolleir will accept women among their soldiery, while to our good guys, the people of Eileanan, female soldiers are unknown and barely conceivable, and Iseult has to put forth quite an effort to be taken seriously as a warrior. This "only villains accept women as soldiers" element has been a sticking point for me in both Brandon Sanderson's Stormlight Archive (which I otherwise adored) and John Gwynne's Malice. If women soldiers are only accepted/allowed in the ranks of Evil, are we meant to view the idea of women soldiers as somehow inherently bad? It seems an odd impression to get from this book, in which so many other forms of female power are clearly embraced.
Second, in a sub-subplot, the son of one of the main villains is about to be forced into marriage, and he's terrified that his bride will be a "big, strapping girl" who can out-ride and out-wrestle him. When she turns out to be a petite damsel, mild and soft-spoken, he's so relieved that he falls in love immediately. When I read this, I couldn't help thinking, "Please, please, let the dainty, delicate maiden turn out to be a shrew," just so the young man could learn that a big, strapping bride isn't necessarily the Worst Thing Ever. Alas, no; the dainty bride is as nice as she seems, and thus the tiresome (for me) "No Guy Wants an Amazon" trope goes unchallenged here. Sigh. Maybe this small detail would bother me less if I got the impression that Lachlan does value Iseult, so at least one guy actually does want an Amazon...
All the same, I'm enjoying this series immensely and look forward to the next books.
