Taken By My Alpha Triplet Stepbrothers

Shannon Hirthe, she is an omega she-wolf without a father to protect her. Suffering from bullying all through high school, she never had a chance to fight back.
Fate has always played tricks on her, and on the day of the start of her senior year, the goddess shows her her MATE in favor of the bully's asshole, Eric, who seizes the opportunity to completely humiliate her…

His nose flared, and his eyes hardened while he choked me, making me unable to breathe. “Accept me, or, die?” He laughed, while my vision blurred, and tears streamed down from my face in suffocation.
I gritted my teeth, and reply loudly, “I, Shannon Hirthe of Mystic Pride pack, accept Alpha Eric Funk of the Howlers pack as my mate!”
“Hahaha, you're ridiculous! Do you think anyone would want you as their mate, Rubbish?” He laughed, biting his lips, and shrugged. “What do you think about it guys, do you want her?”
As the crowd shamed him, Eric said in a cold voice, “I, Alpha Eric Funk of the Howlers pack, reject your OMEGA Shannon Hirthe of Mystic Pride pack!!!”

But the remarriage of Shannon's mother changed her life forever. No one could have imagined that the Moon Goddess would give her not one, but three mates!
But Shannon is afraid to accept them, not only because they're her stepbrothers, but also because of what her mother has always commanded…
-----
“MATE,” my heart pounding as fast as a car engine as my gaze loomed over at them. How could this be?
They're my stepbrothers, and not to forget how much they hate me. Are they going to reject me too?
I gulped, as my mind went blank when Zed pushed me to the wall, baring his fangs just over my neck.
“NO!!!” I screamed as my voice echoed around the hall. I trembled, my tears falling down as I mumbled, «Don't mark me…"

What is the mystery of Shannon? And what does it all have to do with her late father?

Chapter 1 Rejected
(Shannon's POV)
I wished for the vacation to last a while longer. However, it was quick to end.I'm back here again, and this place is supposed to be an academy, but it's actually hell for me!
“It's okay Shannon, it's only a year away, it's almost graduation…” I muttered to myself as I walked through the Academy gates.
I picked up my pace towards my classroom, my eyes constantly darting around, desperately trying to avoid everyone, especially Eric.
Eric was a veteran of schoolyard bullying. I'd been bullied by him and his thugs ever since I came to this school. And there was nothing I could do to fight back, the only way was to hide and try to keep him from noticing me.
Fortunately, everything was going normal, but anxiety gnawed at my insides. Something that filled me with unease.
I took a deep breath, standing just before the door of my class as I pushed it open gently, and peered inside. Everyone was already there.
Of course, Eric was there.
My heart leaped as my gaze matched with Eric's and I immediately gazed down. A fuzzy voice in my head kept screaming, but I couldn't hear it clearly, it was as if the voice was shouting something very hard, but it wasn't loud enough to be heard clearly. I breathed heavily and tried to calm myself, but it was no use.
“Shannon?” who was calling me?
I was in a trance when a roar from the professor interrupted the voice in my head.” Shannon Hirthe! Are you okay?!!”
I swallowed hard, meeting professor's gaze, and gave him a nod before entering the classroom. It felt as though my heart was ready to burst out of my chest any moment as I made my way toward Eric. The only empty seat was beside him, leaving me with no other option than to sit there.
But as I neared him, I felt suffocated, and a scent filled my nostrils. The voice sounded again, and this time it was unmistakable.
“MATE!”
