"What is a river?" an inquisitive young girl asks her grandmother as the pair sits together on the river's banks. Like many questions posed by curious children, this one is deceptively simple in its asking. Yet, its answer spans the very world itself: geography and history, science and religion, industry and environmentalism. Through author-illustrator Monika Vaicenavičiene's eyes, the river becomes a vessel for enormous complexity, a lens through which the interconnectedness of our shared earth can be understood.
