The Bittering family moves to Mars to be safe because there is a war going on Earth right now
Harry, the Dad, wanted to go home and waited for a spaceship to arrive and take them home but none do because on earth there was a bomb that destroyed all the spaceships
Harry had planted a peach blossom tree he had brought from Earth. When the wind blew the blossoms from the tree he picked one up and saw that it was different. He couldn't tell how maybe an extra petal, leaves, smell, or color. Also, the roses were turning green.
Harry started thinking that Mars will change everyone so he started building a spaceship.
One day while Harry and Cora were swimming David came and asked them if he could change his name and when he was saying dad instead of dad he said, Utah.
