The Alpha's Dead Mate

After being buried alive for 642 years by her vampire coven for going astray, Sarah is finally revived by a group of curious teenagers who had come across her coffin. Fangless and hungry, Sarah runs into Adam Richards, a twenty-five years old werewolf, who as she would find out later, happens to be her mate.
The two are so different, yet so alike, but can not be together as the werewolves had a strong dislike for the vampires, so a new girl is brought to be Adam's mate, but Sarah doesn't plan to be replaced so easily.
