I have just recently read a storm of swords and a feast for crows.
Shae is a big departure from her book version and tv verizon. I hope they still end up in the same place.
Also jeyne westerling is different from talisa
The tyrell family is missing 2 important members
The greyjoy storyline is almost totally different.
I am hopeful they keep the important plot points the same. Even if stuff happens out of order, or for different reasons. Like Robb wanting to take casterly rock instead of moat cailin
Edit: also now stannis is like my favourite character and I kind of hate dany now. The guy doesnt want the iron throne, he feels he needs to take it out of duty to his brother robert and his daughter shireen. Also he wants to bring justice to westeros. Robb is an ass for not supporting his claim as his father would have wanted him to. After the baratheon bannerman went over to stannis robb should have pledged his support and moved his forces to delay lannister/tyrell forces from reinforcing kings landing, thus allowing stannis to take the city.
well if that had happened, the books would be over..
Who else would it be? I bet Clarke is the only one that can leverage anything she wants from the producers. All the other women on the show that have been nude can be easily replaceable, Clarke is a Co-star of the show, she can demand anything she wants from the producers.
