Killing Rain by Barry Eisler

Good read, would like to read another in the Rain series.  PW: At the start of Eisler's taut and compelling fourth thriller to feature John Rain (after 2004's Rain Storm), the freelance assassin's latest employer, Israeli intelligence, has sent him and his longtime associate, Dox, to Manila to kill weapons dealer Manheim Levi. Just as Rain is about to make his move, however, Levi's young son suddenly appears on the scene; Levi's bodyguards wind up shot while Levi and his son escape. The dead bodyguards turn out to be ex-CIA; and Jim Hilger, the renegade Company man with whom they were also working, is upset enough to ask his own specialists to exact revenge. Trying to find a way to complete his mission, Rain contacts Delilah, a fellow intelligence agent with whom he's been involved. But her Mossad colleagues, who have lost their trust in Rain's reliability, are setting up their own plan to take care of him.
