If you're looking for a great insight into Bradbury's thoughts on religion and spirituality, this is a must read. The metaphor in this work is as complex and layered as anything I've read from Bradbury in a long long while.

So, If you haven't read it, read it and if you haven't read it in awhile, read it again. I've been loving this more and more as I reread it a 7th, 8th, 9th time.
