I finished the series, finally. It was addictive to the end. In some ways satisfying, in other ways rather frustrating. I wrote a rambling review of it on Goodreads, should anyone care.
I will include a brief snippet here, something that in scanning over reviews of the books I just hadn’t seen touched on at all.
“One thing about the books that I do appreciate is this: In many fantastical pieces of fiction, there’s a central character who ends up being the savior (Harry Potter, Frodo/LotR, Neo/Matrix, Rand/Wheel of Time, etc etc). That character is usually “different” in some way or another that ends up saving everything, and that character is consistently male. It was a breath of fresh air to read something where the character with the awesome powers who saves the day is actually female.”
