A striking debut celebrating the warm bond between a little boy and his dad as they work hard to achieve their dreams Papi is a bricklayer, and he works hard every day to help build the city, brick by brick. His son, Luis, works hard too--in school, book by book. Papi climbs scaffolds, makes mortar, and shovels sand. Luis climbs on the playground and molds clay into tiny bricks to make buildings, just like Papi. Together, they dream big about their future as they work to make those dreams come true. And then one Saturday, Papi surprises Luis with something special he's built for their family, brick by brick.
