WONDERFUL EYE
Something reminds the Hyperboloid of the engineer Garin. And in this novel there are inventors villains, rich men are henchmen and to that similar people. Also probably and on Jack London's novels - same dynamic adventure and taking a plot.
KETS STAR
Really science fiction - art fiction does not contradict laws of physics, mathematics, astronomy. In total it is merged and soldered ideally and beautifully in one work. Also the intrigue is good - till the end of the novel it is unknown and will not even guess who actually these mysterious and so powerful aliens, the good or the evil are born by them to mankind.
