Edge of the Pit - Bill Thesken

Badger Thompson works for a protection agency. Their clients are the richest people in the country and they pay a lot of money to stay safe. He works on the outer perimeter of a security team and is one of the best in the business. From running with gangs as a teenager, and with the US Army in Iraq during the surge, he has a unique set of skills to keep his team alive.
It was a standard operation, a bread and butter job, get a client from one point to another and back again.
Badger works the perimeter as always, and the client is a beautiful young singer, a rising star who is going to a nightclub in the gritty belly of the city after midnight. Everything is going smooth until the convoy is ambushed, and Badger wakes up in the hospital with no memory of what happened.
Everyone else in the convoy is dead, the singer is missing, and Badger is a prime suspect.
The agency is in trouble, more ruthless than the mob, and they'll get answers out of him using any means necessary, if they can only get their hands on him.
He is on the run from the agency, the kidnappers, and the police, and he has to find the girl, or die trying.
