Tamed Omega by Riley Carver

This Omega can handle life on her own. That is, until an Alpha arrives to tame her …
Headstrong Fern has just escaped her abductors and started to build a new life for herself on an uninhabited planet. So when a ship crashes right next to her hut, she’s determined to tell any survivors to keep their distance. Little does she know that an Alpha too stubborn and infuriating to put into words has been delivered to her doorstep. Worse, staying away from him proves impossible. It’s not only the off-the-charts chemistry Fern and Amiran have that brings them together. No, Amiran also breaks the news that an intergalactic war has broken out. As dangerous enemies land on Fern’s new planet, she has no choice but to obey the Alpha’s commands. It’s the only way to survive.
But life is about more than survival. And Fern can’t ignore what’s happening between her and Amiran. How would it feel to give in to the primal urges the sexy Alpha inspires? And could the magnetic attraction between Alpha and Omega lead to something worth fighting for?
