Overall I was really pleased with it. I thought Mat's POV was written very differently from the previous ones, he seemed almost a parody of himself. Like he was trying to be too funny, when Mat doesn't have to try, he just IS funny. That disappointed me a little bit, because if any character had to be ruined, I didn't want it to be Mat. (Because I love him). But hopefully that was just a blip and it'll sort itself out in the next installment. Also I would have liked to see some progress toward rescuing Moiraine, because I'm sure that's going to be amazing. But hopefully he's just saving that for the next book and we'll have a very Mat-orientated book 13!
I loved Verin's revelations about the Black Ajah and generally quite pleased with how the White Tower situation was resolved. Egwene really impressed me in this book too, and there was finally some action in that bit of the story, not just sitting about with endless discussions and Aes Sedai politics. Still haven't been able to figure out who/where Mesaana is after all that happened, although maybe I'm just slow. Very pleased about Elaida being made damane as well, if anyone deserved it, she did! Oh, and I thought Silviana for Egwene's Keeper was a nice touch, and made perfect sense to me, as she was one of Egwene's first converts.
I actually liked Rand's descent into madness, how at the end it wasn't even Lews Therin in his head, he literally was just talking to himself. And the end was totally woth it, he needed to hit rock bottom to be able to sort himself out again I think.
Would have liked a chapter at the end, telling how Tuon (sorry, Fortuona) took the semi-defeat at the White Tower. And I'm so curious generally as to how the Seanchan invasion is going to pan out. Clearly they're not all going to pack up and leave again, so how are they going to work out having damane and Aes Sedai running about? Because I can't see the Seanchan letting all their damane run free, and it's even less likely that all the Aes Sedai will end up collared, or what would be the point in most of the female characters?
Oh, and all the way through I've hated Cadsuane, so I was kind of glad to see her finally put in her place (if I were Rand I'd have probably stilled her the first time she tried to tell me about manners, when she's one of the rudest characters in the whole book!) but I also ended up feeling a bit sorry for her.
I also hoped to hear more from Perrin and Mat, and especially Lan. I want to know how his march through the Borderlands was going. Especially after reading New Spring a while back, I have a bit of a soft spot for Lan. I don't normally like prequels but I thought that gave some good background info.
I'm sure I'll think of more to say later, but this has been quite a rambling post anyway so I'll leave it for now. Hope it hasn't been too jumbled together, but I just kept thinking of more and more things to say!
