The Italian edition of Juan Gimenez' landmark sci-fi saga, originally published in France as Le quatrième pouvoir (The Fourth Power).
From Humanoides (the original publisher):
The odyssey of Exether Mega, a young military pilot caught up in an interplanetary conflict between humans -- under the banner of the Planetary United States -- and the Krommiums. After narrowly escaping an attack by an enemy patrol, Mega begins a perilous journey across enemy lines. Through a series of encounters --with both friends and foes -- Mega discovers she's at the center of a complex, secret experiment to create the ultimate weapon of war. As further clues to her role, identity, and destiny are revealed to her, the powers that be ramp up their efforts to capture her. A spectacular and riveting space opera by the creator of Leo Roa and the illustrator of The Metabarons saga.
