Operation Bayou Angel by Margaret Kay

Just as he prepares to leave on a mission with his team, Shepherd Security Operator Brian ‘the Birdman’ Sherman receives a call from his brother, Bobby, pleading with him to come home to Louisiana to help him. Bobby’s been arrested again and needs Brian to help get him remanded into drug rehab, rather than jail.
Little does Sherman know that his brother is not being completely honest with him.
Brielle Jarboe is Bobby Sherman’s best friend. She is a full-time Bayou Guide, part-time reporter who is chasing her dream of getting a job in the big leagues of journalism. She writes a blog on happenings in the Parish, a hard-hitting, real news, no-fluff blog that has called out people and businesses in the Parish and brought a lot of unwanted attention to herself.
She knows something isn’t right in the Bayou, but she doesn’t know that she has the story of her life, a story that just may get her killed.
Enter Brian Sherman and Shepherd Security.
Shepherd Security recruits only the best. They can protect someone in trouble like no other because they work in the shadows, invisible, and outside the system where the rules don’t apply–just the oath they took. They don’t exist. That’s also why they can break any suspect and can get answers out of anyone accused. That’s when they’re called in, when someone must be protected at all costs, or when answers must be obtained, by any means necessary.
