"Grace Gibson was murdered Mary Grayson, and that's the end of it". Says the policeman that gets killed in a shoot-out a hours later. Mary Grayson lives in a world where lies kill, literally. The more lies you tell, the more likely you will die, so its best to tell the truth and be the nice citizen of District 78 that the government wants you to be. But when Mary is left reeling as her sister is found headless in Merryweather Lane with her husband nowhere to be found, she finds herself plunged into a world of death, evil truths and damn good lies. Are you a liar?
