Rejected By The Beta, Accepted By The Alpha

I am an Omega, the lowest rank in the wolf packs, the rejected, the despised. I never bother about being an Omega or serving my fellow wolves as long as my family is right beside me.
My bed of roses turned into a bed of thorns when I clocked eighteen. I discovered that my mate is the beta, and he has pronounced rejection upon me. My heart is torn and my life has turned complicated. Is this how it feels to be rejected by your mate?
 
Being an Omega is bad, isn't it? Getting rejected by your mate is worse, is it not? And getting accepted by a cursed Alpha is the worst of all, don't you think?
When the Beta, Elena's mate rejected her, she felt her world crumble to pieces. The Alpha crosses her path and her fate gets intertwined with him.
Elena thought her life has turned around when the Alpha came to her rescue and pronounced acceptance upon her. But when she finds out the reason behind his action, will she decide to stay rejected by the Beta or accepted by the Alpha?
