Enter the Dragons?
I haven't read but one of the books, and this wasn't covered it that, so this is not a spoiler; just my speculation. After the Hardhome battle, I think I've figured out, probably along with the rest of you, how this is going to play out, i.e., after the Wites, et. al., make it over the Wall, followed by another, even bigger, massacre, Daenerys and the dragons with save them. I just hope she's riding one of them. If anyone knows if this is true, please don't tell me. I'm not reading the other books because the one I read definitely spoiled some of season 2 for me. I just wonder if anyone else shares my speculation. Or, maybe I shouldn't even be asking this.
