How well do you really know your best friend? Kat Grant and Alice Campbell have a friendship forged in shared confidences and long lunches lubricated by expensive wine. Though theyâre very different womenâthe artsy socialite and the struggling suburbaniteâtheyâre each otherâs rocks. But even rocks crumble under pressure. Like when Katâs financier husband, Howard, plunges to his death from the second-floor balcony of their South Florida mansion. Howard was a jerk, a drunk, a bully and, police say, a murder victim. The questions begin piling up. Like why Kat has suddenly gone dark: no calls, no texts and no chance her wealthy family will let Alice see her. Why investigators are looking so hard in Aliceâs direction. Who stands to get hurt next. And who is the cool liarâthe masterful manipulator behind it all.
