Other editions of book Children of the lens

Children of the Lens is the sixth and concluding volume of the six classic Lensman books, long recognized as the greatest space opera ever written. Twenty years have passed since the events portrayed in Second Stage Lensman. To Kimball Kinnison and his wife Clarrissa have been born five children Kit, the eldest, and two sets of twin sisters. These are the 'Children of the Lens' the offspring of uncounted generations of selected matings. The most capable, the most brilliant minds in the universe. Their job is the conclusion of the Boskonian war, and how they accomplish this end and gain ultimate victory makes up the greater part of the book. (From the 1954 Fantasy Press edition of Children of the Lens.)

It was beginning to look as if no one could prevent the destruction of the Universe. For a strange intelligence was directing the destruction of all civilization from the icy depths of space. Kim Kinnison of the Patrol was one of the few men who knew how near the end was. And in the last desperate plan to save all life, he knew he had to use his children as bait for the evil powers of the planet Ploor.
