A beautiful, lyrical non-fiction picture book about the water cycle.

Issac empties his little jar of water into a stream and follows its journey through the country and the city until it joins the ocean. On the other side of the world, Cassi welcomes the rain in her dry village, where rivers now run and make their way back to the sea. The cycle is complete as the sun heats the ocean and clouds are formed that carry rain back to Issac once more.
