I am reading Faithful Women and Their Extraordinary God by Noel Piper. I love it. It is so enjoyable, telling the stories of women (most of whom were missionaries) who served the Lord, who were sinners, who knew the Bible, and memorized it, and LONGED for God to have His rightful place in people's hearts all over the world. It is so good. I was reading about Gladys Aylward and I forgot that it was non-fiction a couple of times, as it was like an adventure story. My favourite so far is Ahn Ei Sook however.
I need to reread this though, as while I have been caught up in it, I have failed to take application points from these women's lives (which was laid out for the read at the end of the chapters, so I would be remiss not to take note of them).

Also, I think this article is really great:
