Castrillón’s whimsical art is intriguingly paired with the subject matter, incorporating both the explanatory and speculative, using fine lines that seem delicate but are also robust—light but muscular, just like the materials Wade describes. . . . A marvelous spark for the imagination and motivation to learn more.

Exceptionally well-organized and smoothly narrated. . . Wade proceeds from familiar around-the-house scale, down to the molecular level, and then to the mind-bending ultrathin molecular level of nanomaterials, all in terms elementary schoolers can understand. . . a treasure of a group read for teachers and students with minds wide open.
—The Bulletin of the Center for Children's Books (starred review)
An excellent book for getting young children interested in science, this supports classroom studies of matter, the work of scientists, and the possibilities of future discoveries.
—School Library Journal (starred review)
Playful. . . Organic, and often lush botanic, motifs rendered in pencil, in a muted primary color palette rendered digitally, link the spreads, adding a layer of enticement to this accessible read.
—Publishers Weekly (starred review)
Wade, a physicist, breaks the topic down into delightful morsels, introducing young readers to the wonders of nanoscience. . . . Castrillón’s intricate illustrations are vibrant and inviting, equally adept at capturing whimsical landscapes and detailed scientific explanations. An appealing and enlightening introduction to the small parts of a big universe.
—Booklist
Wade presents her material with an appealing rhythm, and Castrillon has created whimsical images that match the hopeful spirit of the text.
—The Washington Post
Wade has a passion and reverence for the subject matter that shines. And she never speaks down to children, reminding them in the end that it might just be “YOU,” the reader, who unlocks more secrets of nanotechnology.
