So begins the imaginary journey of a child inspired by the view outside her bedroom window: a vast river winding through a towering city. A small boat with a single white sail floats down the river and takes her from factories to farmlands, freeways to forests, out to the stormy and teeming depths of the ocean, and finally back to the comforts—and inspirations—of home. This lush, immersive book by award-winning picture book creator Marc Martin will delight readers of all ages by taking them on a transcendent and aspirational journey through an imaginative landscape.
