Season by season, a child learns about Abuelo's past life in Cuba.The young narrator visits Abuelo several times a year, and they always go to the beach near his home. Starting in summer, the child gets glimpses into the life Abuelo led before he fled Cuba. "In Havana," he says, "marlín and delfín would leap right there!" Though he smiles at the memories of pineapple, guava, and coconut ice cream, his reminiscences are tinged with sadness, too. Abuelo won medals for his swimming prowess, but he left them behind in Cuba. He misses his homeland "so much it hurts," but he's grateful to still have the ocean he loves, as well as his family, including his grandchild. This confidently told story, made up of brief moments between Abuelo and the grandchild, gets deeper as it goes on, with richly textured digital illustrations highlighting the changing light and weather as summer, fall, winter, and spring each take their turn. Without ever becoming overly sentimental, the book conveys how past and present simultaneously coexist for Abuelo. The sky fills with clouds shaped like dolphins and marlins after Abuelo reminisces about them, and large medals, like the ones Abuelo won back in Cuba, wash in with the tide. Spanish words are incorporated throughout.A deftly told immigrant's story of bittersweet memories and a grandparent's love. (author's and illustrator's notes) (Picture book. 4-8)
