Kyler el Darkos is an elite Gravasian assassin who answers only to the king of Gravas. His mission: Find Balthazar and eliminate him and any of his associates for their part in abducting the king's son and trying to market stolen Gravasian weapons. His search has brought him to the planet of Mortis and Hell's Gate, a bar owned by Balthazar's father. The last thing he expects is to fall for Etta Mortis—his target's sister—a woman who tempts him to risk his honor for a chance at love.
