Rescued By the Alien Outlaw by Ella Maven

Instead of a white knight, I got a bronze alien…
Rain: My life has never been my own, and that’s never been more true than in the Rinian Galaxy. I’ve always had dreams that led me to believe my life is bigger than being the servant to some snake alien queen, but as each year goes by, I’m beginning to think my subconscious is lying to me. Until he shows up… the Kaluma with one blue eye who I’ve never forgotten. But he’s not who I remember, and it seems this galaxy has broken another soul.
Kazel: I will rescue Rain, and I refuse to die trying. She’s the reason I’m alive, and I always repay my debts, even if it means pretending to be someone I’m not to infiltrate the enemy’s stronghold.
But this won’t be easy. As I embark on the mission of my life, I know it will take all of my wits to rescue the beautiful, strong human and then convince her I’m her future… as her fated mate.
