Ten years ago, Stefan Korsak's younger brother was kidnapped. No one knew who took Lukas, or why. He was simply gone. But not a day has passed that Stefan hasn't thought about him. As a rising figure in the Russian mafia, he has finally found him.

But when he rescues Lukas, he must confront a terrible truth--his brother is no longer his brother. He is a killer. Trained, brainwashed, and genetically transformed into a flesh-and-blood machine with only one purpose--assassination. Now, those who created him…will do anything to reclaim him.

And the closer Stefan grows to his brother, the more he realizes that saving Lukas may be easier than surviving him…
