Sirens of Titan

Vonnegut's a weird guy. I finished Sirens of Titan today and I'm left with the feeling that it is a weird religious meditation on predestination and the Miltonian Satan who was set up by God to be a villain. Except it's a sci fi book with flying saucers and sentient machines.

There are so many ideas crammed in here that I'm not really sure what I think except that it seems to me that Vonnegut is sceptical to the idea that we truly have free will. It seems like in all of his books that I've read that his protagonists always end up manipulated by some form of outside agency that operated in such a complicated system as to appear random at first blush.

I spent about half my read fearing that I'd already read it but it turns out that there are certain ideas that were also in Slaughterhouse V  and I was getting the two confused in my head.
