Chimera

"Ten years ago, Stefan Korsak's younger brother was kidnapped. No one knew who took Lukas, or why . . . . As a rising figure in the Russian Mafia, Stefan has finally found him. But when he rescues Lukas, Stefan 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." -- Cover, p. [4]
