The Cyber Chronicles VI - Warrior Breed. The Cyber Chronicles, #6

After surviving an explosion aboard their ship and escaping a spacial anomaly, Sabre, Tassin and Tarl are dropped off aboard a warship belonging to Trykons, the most warlike human race in the galaxy. Even the Overlords cannot put an end to the Trykons' endless battles for supremacy, and have placed the solar system under restriction. As long as the Trykons only fight each other, they are left alone, isolated from the rest of humanity.
Everything about Trykon society is decided by combat, and they do not tolerate weaklings, even amongst their own race. Non-combatants are considered inferior, used as servants, and not allowed to procreate. Selective breeding has resulted in a race of near giants whose sole purpose in life is to fight for their clan to win control of the planet. When Sabre arrives, unannounced, aboard the warship, his only goal is to take control of it so he can use it to reach Omega Five.
Naturally, command of a Trykon warship is decided, like everything else, by combat prowess. To the Trykons, Sabre's stature is unimpressive, and Tassin, who dislikes being a non-combatant, wants nothing more than to put the arrogant, and very large, Trykon warrior women in their place. While the Trykons are the ultimate warrior breed, however, they have never encountered a cyber before.
