<br/><br/> 'I promise,' said Rosa. 'I won't kill and I won't make anyone else kill.'... I can't see the loophole. Since the guinea pig there's been nothing. Months now without Rosa killing as much as a mosquito...as far as I know. Che Taylor has four items on his list: 1. He wants to spar, not just train in the boxing gym. 2. He wants a girlfriend. 3. He wants to go home. 4. He wants to keep Rosa under control. Che's little sister Rosa is smart, talented, pretty, and so good at deception that Che's convinced she must be a psychopath. She hasn't hurt anyone yet, but he's certain it's just a matter of time. And when their parents move them to New York City, Che longs to return to Sydney and his three best friends. But his first duty is to his sister Rosa, who is playing increasingly complex and disturbing games.
