About the Holiday
As the old proverb goes, “April showers bring May flowers,” but all that rain brings something else—rainbows! The science behind rainbows was first discovered in 1693, when scientists realized that this phenomenon is caused by light from the sun being refracted through raindrops and causing a dazzling show. Today, I wish you a rainy day and happy rainbow hunting! A perfect place to find rainbows every day and in amazing places beyond the sky is in today’s book!
A Universe of Rainbows: Multicolored Poems for a Multicolored World
By Matt Forrest Esenwine | Illustrated by Jamey Christoph
Rainbows are a universally loved natural phenomenon. The excitement of seeing a rainbow arcing across the sky never goes away no matter how old you get. And a double rainbow? For some people, seeing one of those can be like glimpsing a celebrity. In the 22 poems that make up A Universe of Rainbows, Matt Forrest Esenwine and 19 other poets reveal that you don’t always have to wait for rain to be awed by the brilliance of this spectrum of colors as they abound in nature: on land, in waters, on plants and animals, and even in the depths of space.

Nikki Grimes leads off this lyrical odyssey that invites readers to travel around the world and beyond to discover rainbows in many forms. In Grimes’ “Rainbows of Light,” she channels the disappointment of a child facing a rainy day with “. . . No hopscotch. / No soccer. / No softball / no skip rope. . . .” The child “. . . curse[s] the rain” until they “catch the storm’s apology: / sun-drenched strips of color / arch across the sky— / A rainbow! / Oh! My!”
You might think that rainbows occur in nature only during the day, but Joyce Sidman, reveals otherwise in her intricate and arresting pantoum “Along the Zambezi.” Sidman animates a moonbow, entreating readers to take a moment to look as “This dancer will not leap for long / over the span of Victoria Falls,” where “. . . a full moon crowns the darkened hill” while “. . . Mist swirls up in silver shawls, / bending moonlight’s slanting spill.”

Rainbow seekers do not always need to look toward the sky to find the glorious hues of rainbows. In his rhythmic “Reflections on the Pool,” David L. Harrison nimbly combines assonance and consonance to introduce kids to the surprising Morning Glory Pool in Yellowstone National Park. Harrison describes how this hot spring—a “miracle of nature . . . / Blessed with bacteria tinted blue”—once appeared as vividly blue, but now, because of human interference, is developing a “rainbow of colors” as other types of bacteria take over. Together the poem and sidebar provide a concrete example of the value of conservation and a gripping entry into further study or research.

Readers also learn about a uniquely dressed tree, Rebecca Kai Dotlich’s “skirted pinwheel” of a flower, two varieties of birds, and incredible creatures of the sea and land that shimmer and glimmer with the colors of a rainbow. In “Elegant Danger,” Matt Forrest Esenwine exposes the “captivating beauty / with radiant appeal” of the peacock mantis shrimp that has “An appetite of titans. / Attitude of steel.” into space to float within the Rainbow Nebula with poet Georgia Heard.
Each poem is accompanied by a short and fascinating side bar offering more information about the natural phenomena that inspired the work.
Back matter includes a list of recommended books and websites where readers can find more information about the rainbows described in each poem as well as a glossary.

For the twenty award-winning writers who’ve contributed to Matt Forrest Esenwine’s debut poetry anthology, unique rainbows occurring in nature have inspired a wide range of contemplation and poetic form. Some are awe-struck, others hold a touch of humor, and still others are conversational. One thing they all have in common is an ability to transport readers to another place or just the right moment to witness one of life’s most astonishing sights. Through each poem, readers learn facts but they also discover how to observe with curiosity, appreciate the miraculous, and commit to preserving our natural wonders.

Jamey Christoph’s multi-media illustrations mesmerize with brilliant color that tantalizes like a magic spell, slipping through ice crystals, hiding in plain sight, turning pools of water and majestic trees into artists’ palettes, and clothing creatures of the air, sea, and land. You might be tempted to think that these natural phenomenon can’t possibly be so vivid in real life, but take a look (these poems encourage further research) and you’ll find that Christoph’s full-spread images mirror their inspirations. Beautiful and stirring, each page welcomes you to linger awhile.
Encompassing riveting writing by award-winning poets, spellbinding illustrations of natural phenomena, and nearly endless applications for science, writing, and art study and discovery, A Universe of Rainbows: Multicolored Poems for a Multicolored World is a must for school and public library collections as well as for any reader who loves inspired writing and nature.
