Catherine Ling from Chasing the Night returns in Iris Johansen’s explosive thriller, What Doesn’t Kill You.

Abandoned on the streets of Hong Kong at age four, Catherine was schooled in the art of survival, especially during her teenage years when she came under the tutelage of Hu Chang—a skilled assassin and master poisoner. Now her old “friend” has resurfaced. But this time Catherine is playing for another team. As one of the CIA’s top operatives she’s joined the chase for Hu Chang’s most deadly elixir yet. And her biggest opponent, rogue operative John Gallo, makes the hunt far more dangerous as, from the corridors of Langley to the alleyways of Hong Kong, Catherine enters the human soul’s darkest places to protect those she loves.
