In this final tale by the legendary author, Earth is devastated and empty. Everyone has escaped to the moon – except Vasco. Luckily, Vasco has his shadow to guide him, and he finds little green Poco – someone to care for and bring to safety. Nonstop dangers await Vasco and baby Poco at every corner, but Vasco's shadow rescues and guides them through destroyed cities and apocalyptic landscapes to safety. Nonstop, the legendary children’s book author's last picture book, sends a powerful message to help guide us through trying times.
