Sheryl WuDunnThe 2009 book Half the Sky is filled with stories that are heartbreaking and inspiring - and often both. The Pulitzer Prize-winning husband-and-wife team of Nicholas D. Kristof and Sheryl WuDunn gives you precisely what you'd expect from a book subtitled Turning Oppression Into Opportunity for Women Worldwide. There are lots of anecdotes supporting the idea that women across the globe face horrific violence, discrimination, and marginalization. That's countered by personal stories that provide hope for change. And both are supported by statistics and academic studies.

"We think that one of the greatest moral challenges of our time is the gender inequality and the brutality that many women and girls face around the world because of their gender," said WuDunn - who will present a lecture version of the book on October 21 at St. Ambrose University - in a recent phone interview. "We also think one of the most effective ways to address a lot of the inequality is through educating girls and bringing them into the formal labor force ... . And we talk about a lot of these issues by telling stories of women who have been facing these challenges, and of other women and men who have come up with solutions."

But the book is also surprising - in ways that are both very small and very big.
