No can do. Like I say the series is starting to lose me.
That happens to me too. I dropped out on Jordan's Wheel of Time series after four or so, because he was just milking it.
So I get quitting books. I just can't understand quitting the books BECAUSE of some scene from the TV show. The undead fighting wouldn't be cribbed from zombie movies btw, it would be from the 'Chronicles of Prydain' by Lloyd Alexander, which was the source material for Disney's awful attempt at 'The Black Cauldron.'
