It didn't help that by the time I got to read Bitterblue I had almost forgotten everything that happened in Graceling and Fire. I know they can be read as stand alone books but there is so much info you learn in both of the previous books that is good to know.
There was so much intrigue, adventure and discovery in the majority of the book that kept me in suspense and wanting more but the ending seemed to dash that away. So I hope Kristin Cashore writes more books in this universe as it is so full of diverse and charismatic characters, but doesn't cut the endings too short.
