Title: Starfighter
A Navigator is given the name “Abel,” and he's paired with a Fighter who is given the name “Cain.” They are part of the Federated Alliance Fleet, a military force that protects Earth and her colonies, including Mars, where Cain is from. As Navigator, Abel's role is to pilot a ship through space, while Cain, the Fighter, acts as the gunman. The two have to work together, especially in this time of war with the looming threat of the Colterons, an alien race that seeks to take over Earth and her colonies, even if it means decimating all human life. However, Abel isn't initially keen on pairing with Cain, as Cain starts their new partnership by biting Abel's lips, leaving them scarred.
A scar, Cain says, proves that Abel is his.
Abel is thrown off and not sure their partnership is going to work, but even when he knows he should be hesitant around the unknown Fighter, he can't help finding himself attracted by his dominance. Ultimately, after only knowing each other for a few hours, the two sleep together. What begins as nothing more than a physical relationship quickly develops into an emotional one, one that Abel is determined to protect while out on the battlefield. What Abel doesn't know is that this relationship might not have started as randomly as he might have thought, and Cain doesn't realize just how important Abel will be to him.
