Have Space Suit - Will Travel

From the back cover of the Del Rey 9th printing: "Skyjacked - Everything happened at once. One minute Kip Russell was walking about in his own backyard, testing out an old space suit and dreaming about going to the moon - and the next he was out cold and the captive of an insidious space pirate. The whole thing seemed like a very bad dream until he discovered he wasn't the only prisoner on board. Then the reality of the situation became inescapable. He - along with the daughter of a world-renowned scientist and a beautiful creature from an alien planet - had been skyjacked by a monstrous extraterrestrial and they were on their way to the Moon... a journey toward a fate worse than death!"
