Book #12 in the King and Slater series.
"Two abduction attempts on separate sides of the city. A van tries to snatch Tyrell, and two men approach Violetta and Junior in a public park. All at once, it's Code Red. King and Slater don't know who's targeting them, or why, but they have an endless list of enemies from decades spent eviscerating hostiles. It could be anyone. Whoever this rogue force is, they've found a way around every preventative measure. They've done what not even the government could do: tracked down Jason King and Will Slater."
