I haven't read this book but the synopsis is compelling and in reading this excerpt I found the writing to be exceptional. Here's the synopsis that piqued my interest.

"A young man arrives in the Big City with two hundred dollars in his pocket, no English at all, and memories of horror so fresh that he sometimes confuses past and present. When Deo first told me about his beginnings in New York, I had a simple thought: "I would not have survived." And then, two years later, he enrolls in an Ivy League university." In his bestselling book, 'Strength in What Remains' Tracy Kidder shares more about Deo -- who survived civil war in Burundi, narrowly escaped genocide in Rwanda, and is now the founder and director of a world-class, community-driven medical clinic in his native country.
