Boko is a book. He no longer lives in the children's section of the library but has been returned to his original owner, Emily, who, with her two grandchildren Ella and Peter and their friend Stephen, has discovered that Boko can talk, and he tells them of his adventures. Emily has made a big red tote with a clear window so that Boko and his two book friends Sylvie and Big Book can go with them to visit a friend of Emily's who has a farm and where they intend to have a picnic. Previously, the books have always been in backpacks or suitcases and have seen very little, but this time they are excited as they can see where they are going and have a real adventure when a goat runs off with the bag while Gran and the children are enjoying their lunch They have fun visiting all the animals, and Sylvie names a calf.
