In a venture into S.F. from his more realistic themes (though we detect the same serious intent) Mr. Felson writes an engaging fantasy of TexSon, a young Feorian whose forced visit to Earth provides for a profitable exchange of ideas. Travelling from Feor to another planet with his parents in a flying saucer, TexSon, who is quite human, gets the chance to meet Tommy, when their flying saucer is forced to land for repairs. TexSon and Tommy decide to change places for a while (they can communicate easily through the translatophone), but find eventually that each must go his own way. A nice turnabout to compare with the few others there have been on this theme.
