After Being Betrayed, I mated to the Alpha King

For three years, Elara Vance loved Kaelen Croft in silence, serving as his loyal aide and secret mate while he never returned her devotion. When she discovers he was sharing a hotel with her sister the very night rogues left her for dead in an icy river, Elara finally resolves to sever their sacred bond and walk away from the Croft pack for good. But escaping a man who only ever saw her as a substitute proves harder than she imagined, and the truth of her stolen birthright threatens to upend everything. Can a discarded omega reclaim her fate when an even more powerful Alpha King takes notice?
