For more than 25 years, surgeon David Nott has volunteered in some of the world's most perilous conflict zones. From Sarajevo under siege in 1993 to clandestine hospitals in rebel-held Aleppo, he has carried out lifesaving operations in the most challenging conditions, with none of the resources of a metropolitan hospital. Offering a moving blend of memoir and nonfiction thriller, Nott provides insight into the human toll of war, as well as his struggles to return to a "normal" life after each trip.
