I loved this book so much it stressed me out. I felt tangible anxiety while I wasn't reading and stayed up much later than I should of reading. When I eventually did put it down at night my mind was wired and I would just lay there thinking for half an hour (normally I go to sleep very quickly).
Bitterblue is such a strong character and the world she lives in is so vivid and compelling. As she explores the world she lives in I feel as if I am travelling with her and am willing her to uncover more and more. As in most books and movies I think she accomplishes more in a day than most exceptional people could in a week, but that's okay. It's fantasy.
I loved the way Bitterblue pulled Graceling and Fire together and tied up loose ends and a very believable way.
I think there's potential for more books set in this world (perhaps one based on Saf's sailing adventures) but there doesn't need to be. It is a satisfying conclusion to an unconventional series.
I really have enjoyed watching Kristin Cashore's story-telling ability blossom. Graceling was an impressive first novel and but nowhere near as gripping as Fire. And Bitterblue blows them both out of the water.
