Miguel's pet frog, Coquí, is always with him: as he greets his neighbors in San Juan, buys quesitos from the panadería, and listens to his abuelo's story about meeting baseball legend Roberto Clemente. Then Miguel learns that he and his parents are moving to the U.S. mainland, which means leaving his beloved grandparents, home in Puerto Rico, and even Coquí behind. Life in New York City is overwhelming, with unfamiliar buildings, foods, and people. But when he and Mamá go exploring, they find a few familiar sights that remind them of home, and Miguel realizes there might be a way to keep a little bit of Puerto Rico with him--including the love he has for Coquí--wherever he goes.
