Mate Trials

Cora Delta is the Delta pack's alpha's daughter and has a best friend, Natalie, who sticks by her no matter what. On the first day of her freshman year at high school, Cora meets the boy of her dreams, Gabriel Reid, and, by some stroke of luck, he likes her too.
Two and a half years later, Cora and Gabriel have mated and everything's going perfectly. When Cora goes to work one day she doesn't expect anything but the usual to happen, until a guy, Tristan Haynes, turns up out of no where. Cora's wolf insists that he's her mate. But that's not possible...is it?
Soon, Cora's whole life turns upside down when lies unfold and she's told she's going to die. There's only one way to save her, and that's by letting one of her mates die in her place.
