This book has about three plots, tenuously connected, with some clever concepts of alien beings, with pseudosexual innuendoes, dragging-on ad nauseum in inadequately developing a few good guys, and an arch-bad guy, never coming to grips with a real story. Its abrupt end leaves several strings, and lots of subplots dangling and mystifyingly unclosed. Proof that even a "Grand Master" of Science Fiction can, if he types long enough, write a dud. Highly un-recommended. Pulp.
