Jonny is Miranda's younger brother. He is only thirteen, and he loves baseball. Over the summer he goes to baseball camp, where he plays baseball and works on a farm. It is noted that when he comes home he is much more mature. When he gets home he still eats three meals a day, even though nobody else does. He also starts helping Matt cut down trees. In the winter, he gets the most sick, but regains his strength slowly but surely.
