The legendary children's book author's last picture book sends a powerful message to guide us through trying times.

In this final masterpiece from the late Tomi Ungerer, 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. It's a timely, thought-provoking tale of friendship, trust, and hope.
