Moving is scary, but not if you turn it into an adventure! A little boy and his littler brother pretend their journey to a new home is a trip to Mars. They build a rocket ship, equipped with buttons and knobs and bid farewell to their familiar surroundings. Of course, when you visit a new planet, don't be surprised if you run into Martians! How will our brave astronauts deal with the stranger in their midst? All the opportunities for fun and fantasy are here, in a book for young earthlings that's out of this world!
