Phantom by Helen Power

Would you sell your hand for a million dollars? Regan "Roz" Osbourne is broke. Her ex-boyfriend won't take no for an answer, and no one is taking her artwork seriously. So when a mysterious stranger offers her a million dollars and safety from her unstable ex in exchange for her left hand, she can't afford to refuse. ​ Immediately following the amputation, she's racked with insufferable phantom limb pain. Desperate for relief, she enrolls in an experimental drug trial. But this drug has a peculiar side effect—she develops a psychic connection to her missing limb. She soon discovers that Chicago's long-dormant Phantom Strangler is now wearing her hand and is using it . . . to kill.
