The Alpha's Assassin Mate

In front of the moon goddess, I reject you Alpha Conroy, a fucking murdering scumbag as my mate!” He, Alpha King Conroy was rejected by a human- Amelia Whittaker.
Amelia is a human by birth and assassin by occupation. Amelia witnessed the death of her parents at a very young age. She watched in horror how shifters who ruled their human world ripped them into shreds and she vowed to get revenge against the wolves that killed her parents.
During her entire life after being discovered by a Human Assassin’s Leader and trained in his Faction, all she wanted to do was to take the revenge by killing Alpha king Lucas Conroy, the Lycan king of the Valerian hybrid werewolves.
Painstakingly handsome and terribly possessive, Alpha Conroy has been longing for a mate since he was crowned the king of the valerians. It destroyed the Alpha when his long awaited mate rejected him and nearly killed him as his assassin mate.
But the moon goddess had other plans for the rejected Alpha and his assassin mate. What will happen in between their conflicting love story?
