In 1492, during the Spanish Inquisition, Benvenida and her family are banished from Spain for being Jewish, and must flee the country or be killed. They journey by foot and by sea, eventually settling in Istanbul.

Over four centuries later, in 1923, shortly after the Turkish war of independence, Reina's father disowns her for a small act of disobedience. He ships her away to live with an aunt in Cuba, to be wed in an arranged marriage when she turns fifteen.

In 1961, Reina's daughter, Alegra, is proud to be a brigadista, teaching literacy in the countryside for Fidel Castro. But soon Castro's crackdowns force her to flee to Miami all alone, leaving her parents behind.

Finally, in 2003, Alegra's daughter, Paloma, is fascinated by all the journeys that had to happen before she could be born. A keeper of memories, she's thrilled by the opportunity to learn more about her heritage on a family trip to Spain, where she makes a momentous discovery.

Though many years and many seas separate these girls, they are united by a love of music and poetry, a desire to belong and to matter, a passion for learning, and their longing for a home where all are welcome. And each is lucky to stand on the shoulders of their courageous ancestors.
