Autumn whispers - Yasmine Galenorn

The D'Artigo sisters are sexy, savvy ex-operatives from the Otherworld Intelligence Agency. Being half human, half-Fae means their powers go haywire at all the wrong times. When two vampire software engineers approach the three sisters about a missing colleague, they don't expect to find much. But then Grandmother Coyote steps in and their simple missing persons case rapidly devolves into a nightmare of debauchery, slavery and corporate greed. They must infiltrate and destroy an organisation of influential men, led by the shady Lowestar Radcliff, before they're found.
