From Newbery medalist Linda Sue Park, an emotional novel based on a true story. Nya goes to the pond to fetch water for her family. She walks eight hours every day. Salva walks away from his war-torn village. He is a lost boy refugee, destined to cover Africa on foot, searching for his family and safety. Two young people … two stories. One country: Sudan. This mesmerizing dual narrative follows two threads–one unfolding in 2008 and one in 1985–with one hopeful message: that even in a troubled country, determined survivors may find the future they are hoping for.
