I just finished reading Corambis and i really, really loved it! I was a little skeptic about it as I always am about end-of-series books, but I enjoyed it so, so much. The ending was just the right blend and balance for me with these characters.
I did blog about it (finished the post right now) in the most general non-spoilerish way(I think anyway that I managed not to spoil anything) I was able to and just thought I would let you know.
(if you want spoilered feedback from me about it, I don't mind giving it, but I don't know how to make that save in a general comment/post so I didn't^^)
