Mated to Rival Kings

I was the Omega girl no one wanted. I was abandoned as a baby and even my mate rejected me in front of my entire pack, leaving me hurt and humiliated.
Then came the Peace Summit that only happens once every 70 years and I found out that the moon goddess gave me a second chance. Only, it’s not one mate, but two.
Valen Aibek, the sly King of the North, and Darian Callisto, the ruthless King of the South. They have been rivals for a decade but suddenly, they have one thing in common: me. They both claim I’m theirs.
If I choose Valen, the South considers me a traitor. If I stay with Darian, the North invades. The two most powerful men want me and I’m the only thing standing between them and a world war.
How should I choose?
