I've just finished this and was so moved and inspired by it I had to recommend it. I've not read her earlier books but am going to give them a try next as I really loved the way she writes.
Hi OP - yes I was lucky to get a copy of The Invention of Wings as a MN giveaway a few months ago and I thought it was excellent. There's a movie in it I'm sure .. Twelve Years a Slave and The Help (I've seen the first but not the second) have both drawn large audiences and I think this would too.
I thought the novel was even more interesting for being based on the true story of the Grimke sisters .. whom I'd never heard of.
I recommend The Secret Life of Bees by the same author. I read it a few years ago and enjoyed it. I have to say The Invention of Wings surpasses it however IMO.
It's on my wish list as I loved her other books ~ The Mermaid Chair is fabulous. I have a serious Kindle and real backlog of books so I'm trying to work through those before buying any more
