He rules a future in which women are helpless, obedient, and always willing. She comes from a past in which a woman's strength, brains, and courage are unquestioned. The challenge between them is timeless.

Secret Service agent Tessa Camen took a bullet meant for the president. She regains consciousness three hundred years in the future on a spaceship, naked in the arms of Kahn, a fierce warlord from the planet Rystan. He's been expecting her. Tessa was whisked forward in time because her fighting abilities include a psychic talent like none other. Only she can defeat an enemy who threatens Earth. The fate of her home hangs in the balance. Once again, she's called on to serve and protect her nation.

In Kahn's world, women are meant to be ruled but also protected. He can seduce Tessa, but can he own her heart and mind? Can he put aside his beliefs about women to help her train for a brutal intergalactic test, The Challenge? If she loses, so does Earth.

Tessa and Kahn are caught in a war of wills set in a future where survival is a skill, power is an aphrodisiac, and love is a challenge that could destroy everything they cherish.
