Fia The Envoy (The Blind World Series Book 1)

Humankind continues to stumble from conflict to conflict. The masses unaware they are pawns in a much bigger game.
An enemy has lurked in the shade, pulling the strings that continually tear our world apart.
We know the enemy!
But we deny their existence, because we can’t see them.
One family can see them, feel them, and walk amongst them however they have been annihilated. The enemy ensured it!
Alone, persecuted and clinging to the threads of her sanity, Fia Colley lives with her elderly guardian unaware that her life of hardship is orchestrated by outside forces. They mean to sharpen the blade which will strike down an ancient evil.
The isolated victim, pushed to breaking is about to unleash a buried rage that will reverberate across the globe, but she is far from alone as the mightiest of allies rally to her aid.
However the most dangerous clan in the world - The Banshee - watch their every move.
