Spoilers be warned!
You have to be joking! Dany ends up realizing she has to embrace her dragons, and the Targaryn words Blood and Fire, and meeting a Kahl she knows in possession of a dragon she has just called from the sky and used to ride down Dothraki like dogs. If she does not end up smashing the slavers with a Kalisar at her back upon dragonback I'll be astonished - which isn't to say it won't happen this is GRRM afterall.
Reek was brilliant and again GRRM managed to make me sympathetic to a character I had dearly wanted to see dead. Circe's commupance was great, lets hope there is more. I was a little surprised to see a new Targaryn thrown into the mix, though I thought it was well done - did you really need to make things more complicated George?
Overall I thought it was a great book, it felt action packed and I cannot think of anything I would have liked cut to advance things further. Looks to me like the next book will begin with the battle at Mereen and then hopefully see Dany in Westeros.
