Realistically, I kind of want to give it 4.5 stars. The characters & writing hold up, the story was unpredictable enough to keep me intrigued & guessing about how she'd wrap it all up, and the ending satisfying, if a bit heart wrenching. My only quibbles are that books #2 & #3 both felt just a tiny bit slow in places--at times it felt like there were long stretches where I didn't see where things were going. Not to say that nothing happened--plenty was happening; it just didn't always feel like it was moving the story forward. Also it's a complicated story, & in retrospect there are some things where I felt either like the foreshadowing could have been paced better.
BUT, overall, a really excellent, interesting, well-written high fantasy series.
