A slice of indulgent escapism is what I'm really craving right now, so that's great to hear!Those Mitford books are some of my favourites, they are my comfort reads when I just want to pick something up and get lost in it for a while. I reread them often.
Not seen the TV show, I am scared it will spoil the book.
And that's fair enough, I think, from what I've read, that fans of novels didn't love it. It just scratched a particular itch I had, in my case.
