Cursed (The Guardian Chronicles) (Volume 1)

Half-succubus Jazz Watkins spends her nights knee deep in Chicago drug dens hunting Suecai?an evil kind of incubi and succubae who devour the souls of humans. But when a leader of the Suecai curses her, Jazz has to track him down. Either she kills him before the curse burns through her, or she?ll become a full-fledged, out of control, soul-sucking monster. She?s got a handful of weeks, absolutely no leads, and only her sexy best guy-friend, Khan, covering her back. But will the growing attraction she feels for Khan get in the way of her mission to save her own life?
