The Alpha's Shadow Mate

Rejected and exiled by her fated Alpha King mate for being a powerless Omega, Elara discovers a hidden, forbidden power within herself. Years later, hardened and formidable, she must confront her past, her mate, and a rising darkness that threatens to consume both her old pack and the man who broke her heart.
Characters:
Female Lead (FL): Elara
Starts as: An 18-year-old Omega in the Silver Moon pack. Orphaned, kind-hearted but physically weak, constantly bullied by higher-ranked members, especially the Beta's daughter, Valerie. Seen as almost packless, doing menial tasks. Her only hope is finding her mate. (Hits: Orphan, Poor Girl/Low Status, Bullied, Omega).
Becomes: A resilient, powerful shifter with a rare, hidden ability (e.g., shadow manipulation, connection to lunar magic thought lost). Trained, physically capable, emotionally guarded but fiercely protective of those she cares about. (Hits: Kickass Heroine, Hidden Identity).
Male Lead (ML): Rhys
Role: The Alpha King of the Northern Alliance (overseeing multiple packs, including Silver Moon). Powerful, burdened by responsibility, possibly scarred by a past betrayal or loss that makes him value strength above all else. Handsome, dominant, intimidating. (Hits: Alpha King, Powerful Male Lead).
Initial Conflict: Feels the undeniable Mate bond with Elara but publicly rejects her due to her Omega status and perceived weakness, fearing she cannot be the strong Luna his volatile kingdom needs. His rejection is brutal and public.
Secondary Characters:
Valerie: Beta's daughter, Elara's main tormentor. Represents the pack's cruelty and adherence to hierarchy.
Kael: A kind Beta or warrior from Elara's pack who showed her small kindnesses, perhaps feels guilt over her exile.
Master Theron / Anya: A mentor figure Elara finds after her exile (hermit, leader of a hidden community, another rare shifter) who recognizes her potential and trains her.
