Valley of Destiny by Ella Blake

Cleo
I survived a crash landing, killer storms, and a valley full of suspicious aliens. I can handle anything. Except maybe the mate bond I never asked for. The lord of this hidden valley saved my life, gave me purpose fixing their broken tech, and somehow wormed his way past every defense I spent years building. But I’m nobody’s property. When rescue arrives, I’ll have to choose: the stars I’ve always called home, or the Rezor, who makes me believe in destiny.

Rezor
The moment the human woman fell from the sky, I knew my carefully ordered world was over. Cleo is brilliant, stubborn, and utterly terrified of being caged. She fixes our ancient systems with clever hands and challenges every assumption I’ve ever held about leadership and love. I would give her anything, even her freedom. But the storms are intensifying, breaching defenses that have held for generations. My people need me to protect them and I need her. When her people arrives, I’ll have to let her go. Even if it destroys me.
