Fuckken loved that series. Not sure I have a favorite book, though. Which one was it, though, that focused on that bitch the whole time? Pillars of Creation? That one sucked.
Also, don't listen to the haters. Every time I've seen this series brought up on 4ch, it was instantly flooded by trolls. Mostly wannabe philosophers and christfags, upset that their worldview has been challenged. The biggest complaint seems to be that the series gets a bit preachy at the end and some people can't deal with the message.
My advice? Don't come back to 4chan until you've finished reading them and have made up your own mind. Don't let trolls ruin it for you. Speaking of which, since you've admitted to not being done yet, there will inevitably be spoilers further down.
