Love, physics and the atomic bomb come together in this month’s Southwest Book Review of Nora Gallagher’s novel, Changing Light. The setting is Los Alamos, New Mexico, 1945; the tail end of World War II and the debut of the atomic bomb. Two characters haphazardly find each other: one love sick and one radiation sick. Their bond takes them into passionate—and dangerous—territory. KNAU’s Mary Sojourner has more.
