Last Man Standing: David Baldacci

Web, an FBI agent is part of a group assigned to take out a drug operation. Upon entering the ally a little boy is sitting there and says "Damn to hell" which causes Web to freeze as his men are all shot to death by automatic machines. Digging deep into the criminal underworld, Web finds out his psychologist was in on the raid and had his office bugged. He implanted the phrase so Web would freeze, though he was supposed to die too. The little boy at the entrance is kidnapped so the Drug lord the group was trying to frame could be manipulated. Everything ends at a horse farm that Web ends up on protecting a family from the past because a white supremist who was responsible for killing the couple's son was freed and people involved with the trial were getting killed. Turns out the wife was responsible for the deaths of the lawyer and judge, but was unaware of the little boy being kept at her house. By the end all the bad guys/ girls are dead and the little boy make it back to his drug dealing father, who we assume is getting cleaned up.
