In the grand tradition of science fiction narrative represented by the best of H.G. Wells and Jules Verne, The Invincible describes the story of a space cruiser sent to an obscure planet to determine the fate of another ship whose communications with Earth have abruptly collapsed. On Regis III, Navigator Rohan and his crew encounter the classic quandary: what course of action can man take once he has limits of his knowledge? The question of inexplicable, the bizarre, the problem that lies just beyond analytical reach are woven into a science-fiction plot that sustains excitement to the last."--Back cover
