Rejected by the Alpha King

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.

He whispered those three little words... "I reject you."

Brie 
I've always known my divine purpose, and it isn't settling down with my fated mate! 
In fact, I can't, not when my sole responsibility is to ensure my little sister, Maeve, ascends the throne as Queen of Eastonia with a peaceful kingdom and strong allies supporting her… 
Which means I needs to marry--and marry well. 
But my hunt for a high-profile, influential Alpha for a husband comes to a grinding halt when I'm forced to spend a month in Maatua to cool off and clear my head at the urging of my parents. 
It's either that or join a convent—no thanks!
No one understands me, but then, that's not new! There's no one like me in my powerful family. Because I was adopted and have no special gifts.
I'm just me—just Brie.
Logan
I know a thing or two about losing everything. Washed up on the shores of the southern Deadlands as a child, I lost the only home I ever knew and the parents I loved, all in the blink of an eye. Now, I've become a fierce warrior and a hardened captain in Eastonia's Ghost army. I serve directly beneath Commander Evander of Veiled Valley, who trusts me more than anyone in the ranks.
So, when the eldest princess of Veiled Valley needs an escort–a bodyguard–during her week-long journey to Maatua, I'm tasked with the challenge of a lifetime. 
Keeping me mate out of harm's way. 
When the line between what I wants and what I need blurs, I can't help but question everything.
Should I stay and fight for Brie? Or will fight for my rightful title… the Alpha King of Emberfyll?
