Yes I recently read this book and loved it, in fact it did remind me of To Kill a Mockingbird so much I went out and ought that too and have just started to read it tonight!
It is a truly, deeply moving book. I would recommend it too!
I would also recommend A Long Way From Paradise by Leah Chishugi, another book that shows women rising from prejudice and adversity to survive. It is set in The Eastern Congo to start and takes you through the genocide of Rwanda. Challenging at times but well worth the read.
