New mother and climate refugee Aileen Dupree has been abandoned by her partner in post- industrial Detroit. Her neighbor, Virgil, is Aileen's only connection to the outside world. But then Virgil borrows Aileen's prized possession - a chrome and leather, royal blue fourteen-speed bike - and disappears. Looking for answers, Aileen hears strange stories of the Elf, a timeless being that always fought the colonizers and capitalists of Detroit, and now leads the Night Roll on a race through the city's disintegrating streets. It is up to Aileen to brave the strange magic of the Night Roll and bring Virgil back. But what can the Elf teach her about her new life? And what must she pay for that knowledge?
