She Doesn’t Ask for Permission. She Just Kills


Department 89 is Germany’s most secretive black-ops unit—called in when diplomacy fails and bullets are cheaper than negotiations. Led by Major Sophie Decker, a ruthless operative with zero regard for politics, this elite unit handles what the government can’t admit exists.

In this explosive 4-book boxset, Decker:

  • Hunts a traitor in Berlin.
  • Wages war against her own past.
  • Fights a North Korean assassin sent to Germany.
  • Captures a US Embassy officer who committed murder.

No rules. No oversight. No second chances.

If you like savage heroines, covert wars, and plots ripped from the headlines, this set delivers pages of pure adrenaline. Perfect for fans of Jason Bourne, Jack Reacher, and cold-blooded women who shoot first.
