There is no doubt that Little Card, a round-edged rectangle with tiny blue sneakers and four-fingered hands, is destined for greatness. Residing in a three-story stone building with his buddies azzy Round Card, the price tag; boxy Giant Card, the manila folder; and flip-flop-flaunting Wide Card, the postcard C. eagerly awaits the arrival of his "special letter" and its momentous decree: "Congratulations! You are a birthday card." However, after only a few days of birthday-card school and its painstaking devotion to baking, surprises, and song, L. C. is hit with troubling news: his letter was switched with another card's! L. C. was never meant to be a birthday card but, rather, a library card. Although the silence of his new environment is initially daunting, L. C. learns fast that the library is an enchanting place, home to friends, cookies, adventures, and surprises of its very own. Raff's minimalist illustrations, splashed in delicate pastels, and Harper's playful text conjure up a world as buoyant as it is endearing.

Little Card and Long Card wonder what their grown-up jobs will entail. After a mix-up, each finds the perfect profession: library card and birthday card, respectively. The original premise is visually well realized in cheery illustrations that incorporate ink washes, stamps, and digital textures. The celebratory tale breathes new life into the theme of paper in the digital age.

PreS-Gr 2 Little Card mistakenly believes himself to be a birthday card and goes off to train at birthday card school. He loves the parties, cakes, and singing, so he is disappointed when the mistake is corrected and he is delivered to the job he was actually destined for. After being shushed for yelling, "Happy Birthday" in the library, he is given to a little girl as her first library card. He loves his girl and absolutely everything about the library. There are games, snacks, and fun, colorful books. The best part is that while a birthday comes only once a year, the library is open year round and any day can be a library day. Illustrations are ink wash with some digital coloring. Little Card is expressive and endearing, and in some instances, his exuberance can barely be contained. VERDICT A good addition to library-themed storytimes. Kelly Roth, Bartow County Public Library, Cartersville, GA
