It's no ordinary day at the castle! This beautifully illustrated, silly picture book is a fun introduction to the medieval world and the illuminated bestiary Godfrey, a peasant boy who works for the lord and lady of the castle, finds a bestiary, or illustrated book of beasts, on the way to do his chores one morning. He begins inventing his own story, placing "Sir Godfrey" at the center of numerous heroic deeds. Sir Godfrey battles a lion, tames a unicorn, defeats a griffin, conquers a bonnacon, and triumphs over a dragon. Godfrey does not realize that each time he says the name of an animal, it magically emerges from the book, causing mayhem and inadvertently accomplishing his chores. The laughs pile up and the tension mounts: When will Godfrey realize that all this outrageous stuff is going on? This book also contains engaging backmatter with information on life in the Middle Ages and a mini-bestiary drawn from original 13th-century manuscripts. Don't Let the Beasties Escape This Book! is a humorous introduction to the medieval world.
