During Megan Buskey’s childhood in Cleveland, her Ukrainian-American grandmother Anna regaled her with tales of growing up in Siberia and a small village in Ukraine. But Anna hid some of her family’s past. When Anna died a decade ago, Buskey traveled to Ukraine, met distant relatives and dug through archives. She tells The World’s host Marco Werman about what she uncovered, and her new book, “Ukraine Is Not Dead Yet: A Family Story of Exile and Return.”
