“Truly this contains some knights to remember.” — Kirkus Reviews A bumbling triceratops must prove himself worthy in New York Times bestselling author Mo O’Hara’s second hilarious picture book offering a prehistoric spin on the legend of King Arthur. It’s the Festival of the Stone, and dinosaurs from across the land will try to pull the great horn Rex-calibur from the magical stone. The one who succeeds shall be crowned king or queen. Arthur-a-tops is probably the least likely to accomplish the task. And yet…could he be the one true king? In this completely reimagined Camelot featuring dino-squires, the trusty Merlin-a-dactyl, and easy-to-trip-over dinosaur tails, O’Hara transforms this classic tale into an enjoyable, accessible, and truly funny treat for young readers. Coupled perfectly with Andrew Joyner’s expressive and classic illustrations, this story will induce fits of giggles and lots of knowing nods from parents who want their little geniuses to have the classics down by first grade.
