Long time geek, fangirl, mother, and reader. I've got a lot to say, you might not like it all, but it will be honest and hopefully helpful.
The scene where Shireen meets Wun Wun, the giant, was AWESOME! I would really love to see this scene in the tv show. I have a lot of love for Shireen, much in the way I love all the Baratheon women (not the wives, but the daughters). But also because she's smart and resilient. As Tyrion says,
"I have a weakness for cripples bastards and broken things."
I always come back to this quote, time and again, because these are the characters who are the ones to watch. The ones who are overlooked by the world, and traditional stories. GRRM has made them the champions in his world. I think it's an important thing to remember while reading, never underestimate characters like Shireen.
