Skylark of Valeron

Skylark Series, Book 3 of 4

As the mighty spaceship Skylark roved the intergalactic world, scientist Richard Seaton and his companions uncovered a world of disembodied intelligences. A world of four dimensions where time was insanely distorted and matter obeyed no terrestrial laws . . . where three-dimensional intellects were barely sufficient to thwart invisible mentalities!
