The first rule of paranormal dating: never fall for a fallen angel. Vesper Emery isn't a soft and cuddly type of girl. A butt-kicking bounty hunter, she spends her nights tracking down demons... and her days alone. When she's forced to take on sinfully handsome fallen angel Kirael as her next assignment, Vesper has no idea just how hot things are about to get... Alpha bad boy Kirael never saw gorgeous, thorny Vesper coming... mostly because she's trying to tackle him and stab him with her sword.
