Wonderful Jane Yolen has written simple poems describing shapes in nature. The poems are matched with beautiful photographs from nature. For example, on the page of the spiral shape is a snail clinging to a lovely lavender flower. "Tight as a spring" begins the poem. To illustrate the oval shape there is a crisp photograph of a bird's egg sitting alone in a nest. It's the shape of an ellipse, an ovoid, an oval. This is a lovely book that reveals all the geometric shapes in the natural world all around us.
