An Ethical Guide to Murder, by Jenny Morris

In her mid-20s Thea discovers she can tell how long people have to live, just by touching them. The shocking discovery that her flatmate and best friend has less than a day left triggers a power to transfer life from one person to another. Ruth is a doctor and a thoroughly good person, surely she deserves to live more than most and definitely more than the idiot responsible for the head injury that will cause her death. But where do you draw the line? Thea starts writing an ethical guide to navigate her power; she needs rules, especially when old crush Sam is on a mission to punish the wicked and recruits her as chief executioner. This is a fascinating examination of ethical dilemmas and moral relativism, wrapped up in an entertaining tale with an ending that is inevitable but not at all predictable.
