The Lion and the Mouse by Emmy Chandler

When she was four years old, Syrie Montgomery was nearly killed when she got lost on Ratera III, the global zoo her family owns. Eighteen years later, she’s back, kidnapped from her bed and abandoned in the location of her childhood trauma—the expansive Fetoji habitat.
Terrified and alone, Syrie runs right into a trap and finds herself at the mercy of the creature who set it—a huge leonine hunter who both scares and captivates her in equal measure…
Deep in the woods, Lohr discovers a rare bounty in his hunting net—a tiny, helpless human woman. She begs him to set her free. To keep her safe while she’s stuck in his habitat. And she promises to return the favor, as soon as she can.
Lohr scoffs at her offer. How could this mousy little human with blunt teeth and no claws possibly be any help to him? He frees her because he needs his net back. Which is when he notices that she’s soft and pretty. And that she smells good. And that she feels amazing tossed over his shoulder, when he carries her to his home. For her protection, of course…
The lion and the mouse develop an instant, sizzling chemistry—but can their passion survive once he realizes that her family is the reason he’s spent his entire life as a zoo exhibit?
