Ohh, I just finished the Poisonwood Bible and it was fantastic. You'll love it. I am also reading A Voyage Long and Strange which is about the discovery of America and alot of it pertains to the Christian influence and treatment of the American Indians. It's written in a way that is insightful, yet often vary amusing.
I am currently reading "Anvil of the Stars" by Greg Bear. I enjoyed "Forge of God" a lot more. must admit I am struggling to get into Anvil and I'm already more than half way into it. Will see where it takes me. Next in line is "Parenting Beyond Belief" by Dale McGowan (thanx for the recommendation on here) and then I'll return to Isaac Asimov again ( been trying to re-read a lot of his books, Just finished robots1 through 4)
Looking forward to finding more good suggestions on here
