For a long time we've needed a book that helps children understand what it's like to break an arm or a leg, and here it is. Miss Kate Larkin unfortunately breaks her arm and goes to the hospital. She ends up in a cast and has all the discomfort of not being able to do all the things she ordinarily does. Along the way, you learn a lot about bones and our bodies. For example, did you know that osteoblasts build new bone from one side of the break to the other and that osteoclasts dissolve the sharp edges of the broken bone? Cool, huh? There's more where that came from.
