My selection is "Swirl by swirl: spirals in nature" written by Joyce Sidman and illustrated by Beth Krommes.
"A spiral is a snuggling shape." Thus begins Sidman's unique pairing of science and free-verse poetry in this festival of spirals from the delicate whorls of a fern to the classic beauty of a chambered nautilus, from a spider's web to a galaxy and an abundance of examples in between. Sidman collects, describes and explains their properties and purposes without ever lecturing the reader. Rather she invites her audience to explore, imagine, and celebrate one of nature's most abundant and powerful shapes.
Krommes' fills each page with elegant line, subtle color and an abundance of detail for readers to study and enjoy.
