He slips through the unlocked window. Creeps down the hall. A shadow standing in the bedroom doorway. Will you wake when death comes ripping?

A string of brutal home invasion murders terrifies Dade County, Florida. The killer strikes in the dead of the night, savages innocent people in their beds, wipes out entire families.

He attacks at random. Rich. Poor. Young. Old. No one is safe.

When the city sleeps, he comes alive. Stalks the night. Walks among us.

The investigation is hopeless. There's little physical evidence to work with, and the killer's chaotic behavior makes him as unpredictable as he is dangerous.

What drives someone to such violence? And how can anyone make sense of such brutality?

The task force leading the investigation needs a profiler, and there's only one man for the job.

Loshak. Special Agent Victor Loshak.

The 53-year-old likes his Dunkin' Donuts coffee shaken, not stirred. And now, for the first time, he's on his own.

But how far will this case push him?

In recent years, Loshak has slowed down some. He relies on more wit than grit these days, often playing a mentor role to his partner, Violet Darger. Until now, she always had more than enough grit for both of them.

But Darger isn't around this time, and a killer this aggressive will push Loshak to his limits.

And beyond.

Yeah, he'll need to find that grit again...or die trying.

This pulse-pounding thriller will have you holding your breath until the final chapter. Fans of John Sandford, Karin Slaughter, Michael Connelly, and Lisa Gardner should check out the Victor Loshak series.
