Dreg City, book 1: Three Days to DeadKelly Meding2009

When Evangeline Stone wakes up naked and bruised on a cold slab at the morgue - in a stranger's body, with no memory of who she is and how she got there - her troubles are only just beginning. Before that night she and the two other members of her Triad were the city's star bounty hunters, mercilessly cleansing the city of the murderous creatures living in the shadows, from vampires to shape-shifters to trolls. Then something terrible happened that not only cost all three of them their lives but also convinced the city's other Hunters that Evy was a traitor - and she can't even remember what it was.
