Endless. Detyen Warriors, #5

Dryce has a reputation, and he's earned every bit of it. Warrior by blood. Playboy by choice. He's tasted everything Earth has to offer, and he has no plans to slow down. Detyens die young, and he's determined to go out on his own terms:  smiling, satisfied, and utterly debauched. Until he spots her. Peyton gave up on happily ever after a long time ago. Her job is to study alien tech, support what's left of her family, and avoid smooth-talking aliens with sharp smiles and wandering hands.
And Dryce? He's a walking complication, one who wouldn't know the meaning of commitment if it punched him in the face. But when a looming planetary threat forces them to work together, neither of them can walk away. Not when the fate of Earth is on the line. Not when the heat between them threatens to destroy every boundary she's ever set. To save the world they'll have to risk everything: their lives, their hearts, and the future of the Detyen race.
And the denya bond may be the only thing strong enough to keep the darkness at bay.
