Rejecting My Nerdy Mate

"I, Atticus Fawn, reject you as my mate and future Luna, Autumn River," he shattered my heart. But then I realized he didn't say my last name, right? He said River, not Rivera. I felt pain, but we still connected with our bond because rejecting someone only works if you say their name right.
So, I nodded and stood there in the dark. My mate didn't want me and told me I was not his mate, and there must be a mistake that the moon goddess made putting us together as mates. But I wasn't replying, so I remained motionless and tried to wake up from this awful dream.
This is different from what is supposed to happen. It should be him kissing me and marking me as his forever. But that's not what happened. When I lifted my head, he was already gone. He left me and returned to Anya, my best friend.
Atticus Fawn is petrified when he finds out he has to marry the best friend of his mate. He tries to escape the wedding but eventually realizes that it is useless to do so. He knows that he can never love another woman like he loves Anya, and not Autumn Rivera. He's, however, unprepared for her gentleness and caring nature. Before he knows it, she's forcing her way into his life, and if he's not careful, his heart may be at risk. That is why his nerdy mate is coming her way. (This is book 1 of the trilogy)
