Ravage by A. L. Rook

We promised to stick together. And then they betrayed me.

In a world where more children are being born with special abilities, we were six of the ones kidnapped and hidden away for testing and training.
We banded together and became a family…until one of us was killed.
The others turned on me and left me for dead.
Five years later, and I’m on a hunt for vengeance against the organization that’s still stealing and brainwashing gifted kids in secret. It’s all I have left; to rid the world of this evil. Until I realize that they are in this city with the same goal.
Aiden. Kellan. Jackson. Dane.
Now I need to decide. Do I work with the ones who abandoned me five years ago, or walk away from this city and finish the war by myself?
But once they discover I’m here, I learn they have their own plans for me.
