Every summer, Natasha and her Dad go to the lake and spend the best days of the year in a cabin they built on a raft. She wonders if we could live like that all the time — and that’s how one of the longest conversations with her father takes her all around the world to see how people in big cities and wildest places live on the water. She meets people who live in floating villages and student campuses, who spend their lives on narrowboats and DIY houseboats. She sees water police and floating farms, beautiful palaces, and modest slums on the water. What she discovers is that rivers, canals, lakes and seas not only protect, nourish, and comfort us, but living close to their surface gives us a sense of responsibility for our planet’s resources.
