This was one of the best thrillers I’ve read in a long time. I was on the edge of my seat and read it in one sitting. 

Her employer gives her an identity and target and she must achieve the task set out without giving up her identity or the whole game. She is an expert at gaining access and getting out of situations without being caught. And she never knows who the mysterious Mr. Smith who sends her on assignments really is.

Until it’s clear she is no longer his favorite and she finds herself potentially a target - the cat and mouse game is on. And the first lie wins.
