“Not many monthly comic books come with a glossary, but not many comics are like Unknown Soldier.” The series, published by an imprint of DC Comics, “is about Dr. Lwanga Moses, a Ugandan whose family fled the country for the United States when he was 7. He returns as an adult in 2002 with his wife, Sera, also a physician, hoping to put their medical skills to use in a part of the country that has experienced civil war for 15 years.”
