Susan Steinberg talks with Kristen Radtke about her debut graphic novel, "Imagine Wanting Only This." A gorgeous graphic memoir about loss, love, and confronting grief. When Kristen Radtke was in college, the sudden death of a beloved uncle and the sight of an abandoned mining town after his funeral marked the beginning moments of a lifelong fascination with ruins and with people and places left behind. Over time, this fascination deepened until it triggered a journey around the world in search of ruined places.
