"I love this series! I’m in love with Sadie and Brad! This series keeps you moving through all the feels! You guys can’t write them fast enough for me!" - B. Bade, Amazon Reviewer

The dark side of law enforcement
Exists only in the shadows.
Sadie’s time has come…
Are you ready?

With Brad away at Quantico for his final interview with the BAU, Sadie is brought into a task force set up by DEA Agent Luke Calloway, and three other shadowy figures. This black-project mission bears the ‘Above Top Secret’ classification and will test every fiber of Sadie’s being.

A woman wakes up in an LA dumpster to find the last 24 hours of her life erased with no memory of what happened. She is not alone. A wave of similar crimes is unfolding in the LA area with no explanation. Worse, each victim has been violated with no memory of the event, only the evidence left behind.

This is not fentanyl, rohypnol, or even tainted cocaine… this is far worse. So bad, in fact, that the powers that be are letting Calloway’s team operate without rules or oversight, only a prescribed outcome: find who’s doing this and stop them.

Permanently.

Sadie is about to go as dark and as deep as she’s ever been undercover, into a world few will ever see, on a case where going too far is what’s required when faced with the nature of monsters.

What will become of Sadie Gray, Brad Tulle, and everything they built? They say the road to Hell is paved with good intentions.

Sadie has plenty. And Hell awaits…
