Malachi by AM Cosgrove

Malachi Murdock had screwed up in a very bad way.
He had picked the wrong side. He underestimated the Rann family’s ability to regroup and come back stronger than ever.
The entire thing had almost cost him his life along with Ethan Adams.
He had seen the look in Jack Rann’s face. Jack knew what Malachi had done was nothing personal, but that didn’t matter to the Rann brothers. Loyalty was everything to them. The fact that Malachi had turn his back on their families hundred-year friendship was considered an act of treason.
Now there was no telling the price he and his brothers would pay for the choices he made.
