As may be imagined from the title, Mr. Fenton Ashâs book does not lack for marvelous adventure. âA Son of the Starsâ novel is a complete rewrite of Fenton Ashâs earlier novel âA Trip to Mars. An exciting science fiction adventure, in which two heroes journey on a trip to Mars, where they have various adventures. In âA Son of the Starsâ the heroes, who bear the names Gerald Wilton and Jack Lawford in âA Trip to Mars,â are called Bruce Mortimer and Maurice Somers. The names of other characters have also been changed, and there are major plot differences between the two works. All in all, they differ sufficiently to merit their classification as two separate novels. Highly recommended!
