House of the rising sun - Kristen L. Painter

Every vampire has heard rumours of the mythical place where their kind can daywalk. But what no vampire knows is that this City of Eternal Night actually exists.
And its name is New Orleans.

For centuries, the fae have protected the city from vampire infestation. But when the bloodsuckers return, the fragile peace in New Orleans begins to crumble.
Carefree playboy Augustine, and Harlow, a woman searching for answers about her absent father, are dragged into the war. The fate of the city rests on them - and the responsibilities their fae blood brings can no longer be denied.
