GRRM is the anti-romantic. Fairy tales go to Westros to die.
Over here on IO9 there is a little thread about what will happen to some characters. It has spoilers in it for those folks who are watching the TV show, but have not read all the novels. I really think this captures what A Song of Ice and Fire’s setting is like.
The hate for GRRM’s treatment of characters is there in the comments, as to is the love for the very same cruel, unbalanced, and distasteful setting. I love it.
Picking who will be alive at the end of the next book is a fun game, and I won’t ruin the TV folks day by guessing here. My prediction though is a confrontation between the big two families of Starks vs Lannisters for who gets a solid piece of a Targaren, and then takes the throne. If you think any of those families are out of the running you’re cont considering how sweetly perverted GRRM is.
