Description Caldecott Award winner Brian Floca gives a heartfelt thank you to the essential workers who keep their cities going during COVID-19 quarantine in this tenderly illustrated picture book. We are here at home now, watching the world through our windows. Outside we see the city we know, but not as we've seen it before. The once hustling and bustling streets are empty. Well, almost empty. Around the city there are still people, some, out and about. These are the people keeping us safe. Keeping us healthy. Keeping our mail and our food delivered. Keeping our grocery stores stocked. Keeping the whole city going. Brian Floca speaks for us all in this stirring homage to all the essential workers who keep the essentials operating so the rest of us can do our part by sheltering in place during the COVID-19 pandemic.
