Barry Eisler spent three years in a covert position with the CIA’s Directorate of Operations, then worked as a technology lawyer and startup executive in Silicon Valley and Japan, earning his black belt at the Kodokan International Judo Center along the way. Eisler’s bestselling thrillers have won the Barry Award and the Gumshoe Award for Best Thriller of the Year, have been included in numerous “Best of” lists, and have been translated into nearly twenty languages.

John Rain, the cynical, romantic and conscientious assassin, is back and now working for a new employer-- the Mossad, which needs an operator who can remove "problems" in Asia. But after a botched assignment, Rain is running for his life from both the Mossad and the CIA.
