I'll do anything to keep Earth safe— even marrying the alien king.

When I joined the Earth Federation after the Roth alien invasion, I was put through the most intense spy training on the planet. I took a vow to do whatever necessary to protect humanity, and I meant every word.

So when the opportunity presents itself to make myself the queen of the Roth and steer intergalactic history? I'm all in. My marriage to the newest king of Roth is the perfect chess move, and I can't stop congratulating myself on my new role.

Until our first diplomatic mission gets hijacked— literally— by a species of aliens neither of us have ever seen. They throw us into a gladiator arena, in a battle for our lives.

The Roth King and I turn out to be perfectly matched in the arena… and outside of it. But if we want to survive, we will have to fight our way back home—together.
