From the book opening:

GALAXIES IN THE BALANCE

The famous scientific trio of Arcot, Wade and Morey, challenged by the most ruthless aliens in all the universes, blasted off on an intergalactic search for defenses against the invaders of Earth and all her allies.
World after world was visited, secret after secret unleashed, and turned to mighty weapons of intense force-and still the Thessian enemy seemed to grow in power and ferocity.
Mighty battles between huge space armadas were but skirmishes in the galactic war, as the invincible aliens savagely advanced and the Earth team hurled bolt after bolt of pure ravening energy-until it appeared that the universe itself might end in one final flare of furious torrential power....

JOHN W. CAMPBELL first started writing in 1930 when his first short story, "When the Atoms Failed", was accepted by a science-fiction magazine. At that time he was twenty years old and still a student at college. As the title of the story indicates, he was even at that time occupied with the significance of atomic energy and nuclear physics.
For the next seven years, Campbell, bolstered by a scientific background that ran from childhood experiments, to study at Duke University and the Massachusetts Institute of Technology, wrote and sold science-fiction, achieving for himself an enviable reputation in the field.
In 1937 he became the editor of "Astounding Stories" magazine and applied himself at once to the task of bettering the magazine and the field of s-f writing in general. His influence on science-fiction since then has been great.
