★ ""A valuable message that’s masterfully (and hilariously) conveyed without being heavy-handed...A quirky, relatable, and spectacular emotional journey."" —Kirkus, starred review “Astutely recognizing the universal allure of constant validation, Rex (Tumblebaby) employs a slyly comic narrative and sculptural digital drawings to nudge readers toward a greater truth: real reciprocity thrives on the perspective that everyone brings to the table.”—Publishers Weekly ""An entertaining story with an important lesson."" —Booklist “Rex smartly avoids didacticism in favor of employing humor to highlight the social skills of respectful disagreement and admitting when you’re wrong, making Junior’s plight both pertinent to our time and timeless.”—The Horn Book Magazine
