Ren Coulter is used to working alone. As a special agent in the Paranormal Operations Unit of the border patrol, his mission is to infiltrate the compound of a reputed drug lord named Mendoza and learn the source of a dangerous and addictive new drug. He decides to go undercover in drag, disguised as a glamorous young woman in the hopes of catching Mendoza's notorious roving eye. Yet even before Ren meets the drug lord, he encounters Darzul, one of Mendoza's striking bodyguards. Despite his lone-wolf habits, Ren sees advantages in working together with the man.
Darzul Onaygan has been sent from his home-world of Arzula to blend in with the earthlings and help them fight off the evil alien invaders. Bisexual as most Arzulans are, many even able to switch gender at will, he finds Ren attractive in both his guises. Yet Darzul knows it takes more than hot sex to build a partnership. While outside threats may force them to work together, that alone cannot forge a bond. Trust comes slowly and not without a hitch, but soon they must also rely on one another to survive.
Can Ren and Darzul live long enough to not only to accomplish their mission, but also to become real partners?
