Two more books in the series to go and I'll finally know how the story plays out.

I liked this quote: "I believe it lures people on to acts of terrible evil by whispering to them that they will do good. That they'll make things not just a little better but all better."

Much evil is done by self-described do-gooders who lie to themselves, are self-delusional, or possess a fatal conceit.

Interesting concepts from the story such as that there are no such things as coincidences, there are forces at work doing good (e.g. preventing a future genius from slipping while getting out of a bathtub) and evil, many things are tied together, etc. Also the idea that non-fiction in one world may be a work of fiction in a different world (this concept has been explored by many previous authors).
