Nine ist part of a project, in which children are genetically to become perfect soldiers and agents. But he now wants to quit his life as an agent and live a normal life. Therefore he wants to make one last deal to get enough money to buy his own island and leave everything behind.
Of course his former bosses are not happy to be cheated by their agent and hound him. Nine hides by changing identity and appearance like a chameleon.
Everything gets more complicated as expected when Isabell a young woman comes into his life and unravels his secret. He takes her hostage, because he does not want to kill her.
The book contains typical action elements one would expect for a book which deals with espionage but also kind of a love story. It was very fascinating how Nine adapts to the different identities in a very quick time. In my opinion the book was worth to read but did not convince me completely.
