In this breathtaking thriller, number one bestselling author Iris Johansen showcases one of her most fascinating characters — pitted against one of the most ruthless killers... Abandoned on the streets of Hong Kong, Catherine Ling was schooled in the art of survival by the mysterious Hu Chang, a master assassin and poisoner. Now recruited by the CIA, Catherine finds herself caught between worlds when her mentor develops a formula that is extremely fatal, virtually untraceable — and highly coveted. On the hunt for this prize are a rogue operative, a band of criminals, and a man so evil he kills without remorse. Catherine will do anything to protect those she loves: Hu Chang and her son Luke. But she will have to use every deadly weapon, every double cross, every lethal lesson she ever learned — to prove that what doesn't kill you makes you stronger...
