I picked Aurian up at a garage sale when I was in college. I figured it looked like a great summer read--and I'm glad to say that I thoroughly enjoyed it. I've re-read it several times since, and even when you know exactly what's going to happen, it's still a wonderful story.
And you'll be familiar with the basic plot--girl discovers that she has wondrous powers and abilities (not a surprise, since both her parents are mages), is trained in physical combat (because a girl can't rely on magic to get her out of every scrape), and of course get wrapped up in a twisted kind of love/lust triangle. And amongst the hierarchy and class struggles between the mages and the non-magical people (who I really want to call muggles), Aurian saves the city and then has to flee because she upset the grand plan of the head mage--and all that in the first third of the book.
When I finished Aurian the first time, I was completely dismayed to find I'd hooked myself on yet another trilogy. So I ordered the next two books (and found that there was actually a fourth book about to be released).
Unfortunately, I found the rest of the books to be less enjoyable. It felt like it should've been a whole saga, but instead it was forced into four books. (The last one, especially, the story felt crammed between the covers.)
Still, I find myself wanting to reread Aurian, even knowing that the books to follow can't live up to what I want them to be. And maybe next time I'll just be able to call it quits after reading just the first book in the trilogy+1.
