The great divirce is - not - abut a divorce but the difference between heaven an earth and the ideas and characters are all brilliant and original. I don't really want to spoil anything by giving details - it is just a great great read.
I also recommend Til We Have Faces. It deals with the differences in ritual and psychology between nature religion and philosophy. Or something like that. I've read it twice, and it's still a mystery to me.
Same here.
Read it (it's not long, I'll bet you read it in one setting).
I have my own "one sentence" synopsis, but I'd like you to read it first and then we could freepmail our exchange of impressions.
