Taken by the Leviathan King

I traded my uniform for scales, my mission for a mate. Turns out, saving humanity might mean becoming a monster's queen

One moment, I'm securing the perimeter, the fate of the USS Legacy heavy on my shoulders, and the next, powerful claws dragged me beneath the turbulent, alien waves of Sanos. I'm face-to-face with Krak'zol, the terrifying, undeniably magnetic Leviathan King. He claims I'm his fated mate. His to protect. His to…change. His venom is transforming me, awakening a primal connection I can't deny, even as I fight him every step of the way. He is everything I should resist: a possessive alien king, a monster in the depths. But his touch? It ignites a fire I never knew existed.  

Krak'zol

I never desired a mate—until her. That human fire, that defiant spirit…it calls to the beast within me. Imogen is mine. My venom flows through her, binding her to me, to the Abyss, whether she likes it or not. But Rynor, my own brother, lusts for my throne and the ancient power it holds. He will stop at nothing. To protect my kingdom, to save this fierce, intoxicating woman who is now my queen, I must fight. And if she tries to resist our bond? She'll learn that a Leviathan King always claims what is his. Let her struggle. The fire only burns hotter.

This spicy sci-fi romance is part of the Abducted by the Ruthless Royal: Planet Sanos series and can be read as a standalone. It features a possessive alien king, a fated mates bond, forced proximity, and a heroine who will fight for her freedom…even as she surrenders to the monster who claims her.
