Claimed By the Alien Warrior King by Zara Zenia

When an attack on the palace forces King Thras to rescue human slave Chera, he can no longer deny his attraction to her and will claim what’s his.
Palace slave Chera fears she will be alone forever, but when rogue forces attack and kidnap the princess, injuring Chera, she awakes to find the enigmatic King Thras watching her with peculiar fascination. The newly crowned ruler has always been stand-offish, yet his intentions are clear: he wants her.

King Thras wasn’t ready to take the throne, but he holds the responsibility of ensuring peace in his system. The attack and kidnapping of his sister is an act of war, and it exposes the warrior’s true weakness: his feelings for the human slave Chera. He’s always been able to resist temptation, but when she’s injured and his uxormea appears over his heart, he knows he’s in the presence of his true mate.
Can King Thras secure the safety of his kingdom and the heart of his mate, or will the forces intent on destroying his birthright succeed in ending his rule and his life with his true love?
