Sucked into another world and transformed into a frog, a young boy discovers what it is to be a stranger – a parepidimos – in a land that is not his own. He is stripped of his own identity and given a new name, Puddlehop. Determinedly, he seeks to find his way home, remove his stain, and survive in a world of constant danger, surprise, and wonder – ultimately leading to his greatest discovery of all: by grace we are saved, and not by works.
