Onca's Duty Galactic Arena Cover

Brazilian Special Forces Major Rafael “Onca” Santos is one of the finest soldiers of the 22nd century. A veteran of counter-terrorism combat and urban warfare, Onca faces the toughest challenge of his life when he is shortlisted for a mission unlike any other.

A dozen of the Earth’s most elite Marines, Rangers, Airborne and Special Forces soldiers will be chosen to travel to the outer solar system. And only one will ultimately be selected to fight in the giant alien space station known as Orb Station Zero.

Onca’s path is clear. He must do his duty. But duty to what? To his country, to the military, his comrades, all of humanity… or to himself?

A story of sacrifice, honor and loyalty, the second prequel in the Galactic Arena Series, Onca’s Duty explores the story of The United Nations Orb Project’s Mission Two. It comes after Inhuman Contact and before Orb Station Zero but can be read before or after either.
