The email pinged again. The attachment was a picture of the door to her flat. She reeled. Clasping her hand to her mouth as she retched again. "It was never about the money, Rachel. It was always about you. I could use someone with your skills. I'll be in touch. I know where you live. D.E.M." No good turn goes unpunished When Rachel is spurred to use her computing skills to find an abducted boy, she has no idea that it will bring her to the attention of an anonymous vigilante. Is the vigilante what he seems and what does he want with Rachel? Rachel is coerced by the mysterious D.E.M. to carry out hacking on seemingly innocuous companies, helped by her friends Deborah, Cam and Cam's ill-tempered boss, Dave. As she gets drawn deeper into their world, she tries to find out more, only to put herself and her friends in grave danger. When she finally realises that the mysterious D.E.M. isn't a vigilante at all, Rachel is in a race against time to save her friends and prevent an escalation in the war between Israel and Palestine.
