Forged by demons from her past, she serves justice as justice should be served – swift, cold, bloody.

Rogue assassin Tess Williams is a drifter. No life. No ties. One goal: justice. At any price. In Krakow, Poland, she's thrust into the hunt for a missing woman. It sounds a simple job, yet the city's quaint medieval architecture hides secrets darker than any Tess has ever encountered.

Her investigation hurling her into danger that stalks the shadows like a rabid dog, Tess employs the deadly skill set she forged in Shanghai's ganglands. But the deeper she digs, the more sinister are the answers she uncovers. And the higher the body count rises.

With more at stake than Tess ever imagined, she's plunged into a race against time to save countless lost souls. But one question haunts her - against unbeatable odds, what is she prepared to sacrifice to see justice done?

An adrenaline-charged thrill-ride, Kill Switch is a must-read if you love pulse-pounding action and a troubled hero with a dark past.
