On Sunday, as President Obama's plane touches down in Havana, Cuban-Americans will be watching. Many of them have endured periods of separation from their families since the early 1960s.
Award-winning author Margarita Engle is one of those people. She is the first Latina to win the prestigious Newbery Honor, for her 2008 book, The Surrender Tree: Poems of Cuba's Struggle For Freedom. She is also the author of Enchanted Air, Two Cultures, Two Wings: A Memoir, a 2015 autobiographical book of narrative poetry.
