Stella: The Unwanted Mate

Stella Renouf is the youngest child of Remus Renouf, the last successor of their elders. Her birth brings dismay to her father as Remus wants a male child. She knows that her father doesn't like her as much as he likes her older sister, named Daisha Renouf.
To carry on their family's legacy, Remus made an accord with their Alpha, named Raven Alarick. They decided to bind their families with a marriage between their youngest children. Stella meets Brandon Alarick, the finest warrior of their pack.
They were given a couple of months to stay under the same roof and learn about how to be compatible with each other. Their situation made Brandon's life miserable because he already chooses his mate. He is vocal about his feelings and shows Stella that he will never fall for her, no matter what happens.
Stella is longing for love that her father doesn't give her, and she hopes that Brandon might fulfil it for her. As time goes by, nothing changes with her relationship with Brandon. They were still strangers to each other. As their families noticed that they were unmatched, they decided to change Stella's mate.
Brandon doesn't know what he feels when he finds out their chosen mate for Stella. He wants to get her back, but it is already late. 
How can he get back the woman he tries to send off? Does Stella still want him to stay by her side? Is there a second chance for them to cherish each other?
