A few possibilities:
I've got Bel Canto sitting on my to be read shelf. I don't know much about it; but it's one of those books I picked up because everywhere I turned someone whose opinion I respected was recommending it. Anyone interested in giving it a whirl?
Or else I was raving about Rumer Godden at my blog, Emily suggested perhaps Godden might be a good pick for our group.
I'm about due for a re-read of my fav, In This House of Brede. Or if everyone's read that, I could stand to re-read Five for Sorrow Ten for Joy or the much shorter An Episode of Sparrows. I just finished China Court and so am fresh enough I could discuss it. Or Black Narcissus is next on the list of books I want to read. Too many choices? Probably. Godden has that effect on me, though.
