Best known for their “Adam Link” stories, Eando Binder (the pen name from the brothers Earl and Otto Binder) provide a fairly standard sci-fi potboiler in this novel. Thane Smith, a writer who pens articles debunking flying saucers, is actually an agent for the intergalactic Vigilantes, who monitor the Earth to keep it safe from predatory aliens. One such group, the dwarf-sized Vexxans, are discovered scouring the globe for mysterious radioactive “Seeds” of unknown power. The plot is pretty standard stuff and the characterization is rather dated, but the writing is entertaining enough to move the reader along. While hardly the best sci-fi available, the book can provide a few hours of undemanding entertainment for fans of the genre.
