Streets of Mayhem (Booker) by John W. Mefford

When a white supremacist group blows up a bus, Booker T. Adams is worried his daughter was in there. Luckily that's not the case but still he feels compelled to investigate. Booker has just been fired from his job as a beat cop following a case of police brutality he stopped.
Now he strikes out on his own as a PI and he's got his hands busy trying to stop the terrorist from making more victims.
Booker was a cool enough character with enough of a backstory and supporting cast to make him interesting. There was a generous amount of action as well.
Still, something in the pacing felt off. I wasn't really compelled to keep reading. Also I didn't care too much for the terrorist plot that was a bit too much in thriller territory for my liking.
