I guess this is sort of a BDSM version of Independence Day meets Dawn.When aliens invade, Charity tries to make it home over the mountains and ends up being the last human resistance fighter. She spends 6 months hiding and evading patrols. Eventually she comes to the attention of Melmanon, the alien Commander, who uses his telepathic abilities to track her down and kill her.Only he doesn't kill her. Because after finally catching up to her he discovers something that she never knew - that she is a sexual submissive and something that he never knew - that he is a Dominant. He gets her officially designated as his "torture slave."It actually isn't that dark of a story except that most of humanity has been brutally slaughtered by the time the story starts. And the BDSM aspects were well done by kind of ended abruptly when it becomes a slightly more conventional love story. But not bad for a quick read.
