Having recently made an enemy of one of Belfield’s most ruthless criminals, she knows she needs to watch her back. As Esther finds herself dragged deeper and deeper into a murky world of corporate espionage and black market dealing, it isn’t long before she gets the unsettling sense that she herself is becoming a target. Can Esther stay one step ahead of her enemies in her hunt for the killer? Find out in Vengeance, the thrilling sequel to The Art Merchant.
