The alpha’s catalyst

Catalina Island was the territory of my park and we had been trained not to reveal our identity to humans, but our only fear was the birth of a Primordial Guardian werewolf which was to put an end to all immortals including vampires and werewolves.
My time to take the place of my father as the Alpha male was approaching and my park pressured me to go in search of my mate so I made a decision to leave after the autumn camp which the humans hosted but during the camp I found my mate and imprinted on her. 
'Alicia' I couldn't forget her name as I brought the news to my father who was the Alpha but while I delivered the message we received a sign that the mortal catalyst who was designed to bear the fatal child had shown up on the Island.
I took it on myself to put an end to the mortal catalyst only to realize that she was my mate. I was devastated, I couldn't kill my own mate so I hid it from my park pretending that I was still in search of her.
I stayed away from her in order to keep her safe but that wasn't until I realised that my park had known who it was and knowing they were going to kill her I had to send her far away from the Island.
I was either going to give her up to a human mate and suffer for the rest of my life, or take her despite the difficulties thereby turning my back on my park, or kill her and myself to save the life of my park.
