Chimera

A standalone sci-fi thriller novel written by Rob Thurman, best known for the "Cal Leandros" series. Stefan Korsak is a bodyguard in the Russian mafia who is searching for his long-lost brother Lukas, kidnapped ten years ago when they were children. Finally, Stefan finds Lukas in a sinister institution which has been performing genetic experiments on children, training them to be superhuman killing machines. But 'Lukas', who insists that his name is Michael and refuses to accept that Stefan is his brother, has no memory of his life and no knowledge of the world outside the institute. Now on the run from Jericho, the mastermind behind the 'special' children, Stefan has to win his brother's trust and keep them both alive.....
