"In this Japanese import, the winsome, bike-riding twins from Chirri & Chirra in the Tall Grass (2017) are back for another gently surreal adventure... The twins are identical, with black pageboys, dot eyes, pudgy, rosy cheeks, and Mona Lisa smiles; their delight in the wonders they encounter is pure, unquestioning, and totally infectious. Another charmer." —Kirkus Reviews "This Japanese import is sweetly magical and perfectly in tune with children’s acceptance of the fantastic. Smudgy colored-pencil illustrations are aglow with light and color, whimsically whisking readers along with the rosy-cheeked twins." —Booklist ★ "Another delightful adventure with the adorable twins Chirri and Chirra. ... The gorgeous, fresh colored pencil drawings portray a world of harmony between the girls and the animals. The animals have a fairy-like quality that is very appealing." —Stephanie Tournas, Youth Services Book Review ”A soft, sherbet-hued realm of kindly animals, cozy dens and delicious edible treats awaits in “Chirri & Chirra, Underground” …Like the other Chirri and Chirra books, this one will earn rapturous scrutiny from readers ages 3-8.” —Meghan Cox Gurdon, The Wall Street Journal "unique and highly recommended..." —The Midwest Book Review "The soft-edged illustrations in colored pencils, pastels, and crayons are filled with details that will have readers wanting to pause and take a closer look." —School Library Journal, Lucia Acosta, Children’s Literature Specialist, Princeton, NJ
