Stunning! Fabulous! Amazing!  The simple text is almost poetical as it describes a spiral as a snuggling shape, a growing shape, a strong shape, a clever shape, and the gorgeous illustrations on each page depict examples from nature where spirals are found in the context described in that bit of text.  Labels tucked cozily in among the illustrations offer scientific vocabulary for further investigations.  Informational blurbs in the back offer more detailed explanations of how/why spirals serve the entities described in the main body of the book.  Highly recommended.  Though a picture book intended for young audiences, I could see it finding purpose in high school geometry, art, or biology classes.
