Barb Eklund didn’t choose where she was born. She knew no one could. But her birthplace, instead of being something she was passingly grateful for, became a regret lodged between her ribs like the pain of a torn intercostal. Her parents brought her from Maryland to rural Ethiopia when she was four. Barb didn’t understand what she was leaving behind when she boarded the plane: her stuffed cat Oscar, the season of winter, or the red bike with training wheels she rode when winter was in abeyance.
