Lost Girl (2010)

Bo is a gorgeous renegade. An irresistible beauty. And a deadly succubus. For years, she had no idea what she was - or why every new lover died in the throes of passion. She fled one corpse after another until a chance encounter with the puckish thief Kenzi exposed Bo's existence to the clandestine order of the Fae. This ancient society of supernatural freaks exists outside the realm of mere mortals. Within their world, there are only two sides: Light and Dark. Each member of the Fae must choose who they will serve. But not Bo. Driven to understand her own aura of desire, Bo vows to live on her own terms - even if it means existing in the abyss between good and evil. With the help of the mischievous, but loyal, Kenzi and the handsome shapeshifter Dyson, Bo will use her powers of seduction to unravel the riddle of her mysterious past.
