FBI Special Agent Kira Cross witnesses a mob execution she was never meant to see. Within hours, she's in a safe house that isn't safe, under the protection of a scarred, dangerous ex-Ranger detective named Kristian Cain — a man who kills without hesitation and sleeps with a knife in his hand.

When the safe house is hit by a six-man professional team, they run. When their FBI contact sets them up in a parking garage ambush, they run again. When the Director of the FBI himself tries to have them executed in an off-books warehouse, they realise the corruption goes all the way to the top.

Now they're out of options, out of allies, and out of time. The only way to stay alive is to go public — and go loud — before The FBI Director buries them both.

The truth doesn't hide in the shadows. It doesn't hide in plain sight. It hides in the Darkdown.
