On this installment of ST, our guest is the noted author and journalist Andrea Pitzer, who tells us about her newest book, "One Long Night: A Global History of Concentration Camps." This volume -- which Kirkus, in a starred review, has called "a chilling, well-documented history...of cruelty and dehumanization" -- begins in 1890s Cuba and ends with present-day Guantanamo, covering camps all around the world and throughout modernity. It's a harrowing work based on archival records, massive amounts of research, and extensive interviews that Pitzer conducted while traveling to four different continents.
