Young Otis is forced to question his origin and allegiances, given that his mom, a yellow chicken, is part of the Nuh-Uhs, and his dad, a blue flower, stems from the Yes-Chums. Struggling to find answers, Otis runs away, only to encounter more colors (and cultures) than he could ever imagine, including a giant portrait full of possibilities. Otis Grows is a picture book, rooted in the challenges of family conflict, but appealing to any child--or adult--who knows that growing up can be tough, that there is "the odor of growing older," but that ultimately, love and wonder will win.
