Ice Cold Kill, by Dana Haynes

This fast paced suspense novel features hero Daria, a former Israeli agent who now lives in Colorado doing private security work.   She's an adrenalin junkie and likes action.  Asher is a brilliant bad guy, who Daria had imprisoned four years earlier.   John is an intelligence analyst for the CIA who becomes a hero.   Sure there are some plot holes, but that's the name of the game in this genre.  I really enjoyed this novel and look forward to reading Mr. Haynes' next one too.
