Onkalot; Death Bringer Book I - Zodiac Universum, #1

After the extermination of the global government and the destruction of its army, the Kiritians seize power on the planet. Colonies of the Milky Way and Andromeda are rapidly falling under the onslaught of a super-virus-infected militarized nation. No one can overthrow the Immortals who have been led for centuries by Forkis, the First Galactic Dignitary. The Kiritians are only opposed by the opposition from the free planets with a rebel navy.
Brought up to hate the Immortals, Second Lieutenant Anna Sandstorm vows to take Forkis's head in order to make up for the harm the usurper did to her in her childhood. The opportunity for this presents itself during the upcoming space battle and later on the wild planet Aj. The footsteps of Kiritian are also followed by a Jaguar-man, Q'ualel, who, having the clues of the ancient Nimja race and a powerful biological weapon, has a chance to change the balance of power in space.
