Op-Op the Triceratops: A Cretaceous Christmas Tale tells the story of a young dinosaur who, like all young boys, dreams of getting just what he wants for Christmas. When he gets something else, Op-Op starts on a journey that will teach him what is really important in this world. Op-Op the Triceratops is both a dinosaur story, a Christmas message, and a lesson about brotherhood. Op-Op is designed for children ages 4 to 8. It is illustrated in a quirky, emotionally resonant style by Beth Tomashek, a young talent and former English student of Martin’s.
