Martha is a very cute woof that an amazing thing happens to-her people feed her alphabet soup and the letters go to her brain and she speaks. She has so much to say to them but she doesn't know when to be silent so finally they tell her to "shut up". She doesn't speak for days but when she needs to she's unable until an unexpected event occurs. I can't give the ending away. Very cute drawings and a good book to talk about the words we speak and why it hurts others' feelings when they're told to shut up.
