Claus

The fierce alien warrior needs a human bride.
 
On war-torn Earth, former interstellar translator Aubrey struggles to raise her late sister's three young boys. It's not easy when resources are scarce, her hometown is embroiled in civil unrest, and her ex-fiancé keeps causing trouble. But she's determined to make a happy life for her nephews. Whatever it takes, she'll keep them safe and fed and ensure they feel loved. She also hopes to make the upcoming holiday season as magical as possible.
 
Vaxxlian warrior Claus is on a mission to find a human wife. He signs up for Vaxxlian Alien Mail Order Brides and travels to Earth, only to learn his assigned mate has tragically passed away. The petite female who delivers this news is the sister of his intended mate, and Claus is quick to propose a marriage of convenience between Aubrey and himself. He promises to always take care of her and the children. Unfortunately, the stubborn human woman is suspicious of his motives. She's also reluctant to leave Earth.
 
Aubrey is shocked by the arrival of the musclebound alien warrior, and she doesn't know what to think of his persistence. No matter how many times she sends him away, he keeps coming back. He also seems to have won over her nephews. To further complicate matters, she cannot deny her growing attraction to the handsome alien, especially after he chases her ex-fiancé away. And when he dresses up like Santa and hands out presents to her nephews on Christmas Eve? Be still her heart.
 
But can a marriage of convenience between total strangers really work?
