Lucía loves to watch the monarcas' annual migration with her papá. But this year, their flight north holds extra weight: Papá is heading north, too, to work on faraway farms to feed his family. Though she hates to see him go, he leaves her a song and a promise that when the weather turns cold and the monarcas return, so will he. After many months apart, Lucía watches the skies for a flicker of hope, the monarchs' homecoming that signals Papá's return. Told through the parallel stories of the butterflies' journey and Lucía's migrant farmer father, Cynthia Harmony's 'A Flicker of Hope' is a love letter to the power of families and nature, both of which know no borders.
