Ok then...I finished reading the last volume last weekend, just before I had to send my Iliad away for the battery upgrade, and now I've finally found some time to write a few words about the series...
First of all, it really is a nice trilogy. The story is interesting and it keeps you interested until the very end. There were a few things that I did not like, some of the characters were a bit too stereotypical, some plot twists were too transparent, some logical mistakes here and there and so on, but nothing major.
I have to disagree with you about the last volume...the first half (or even more) of that book seemed rather weak compared to the other volumes, it felt like there were a lot of rewrites and edits done, sometimes even as though two different authors had tried their luck on certain parts of the story and then just pieced it together. At this point I was starting to get worried...hoewever, the second half of the last volume then goes back on track and finishes the story off nicely, so all in all it's a good conlusion to the series.
Libba Bray is an Author worth watching, at the moment I would not place here among the big ones, but it may well be that she will be among them soon...time will tell.
At this time I'm putting more confidence in Brandon Sanderson however, both as author for the final Wheel of Time novel and as author of solid Fanatasy literature.
