Crescent City Tome 1 (Relié)

Bound by blood. Tempted by desire. Unleashed by destiny. Bryce Quinlan used to light up Crescent City, partying all night in the clubs where the strict classes of angel, shifter, human and Fae merge into a sea of beautiful bodies. And then a demon murdered her closest friends. Two years later, when the supposed killer is behind bars but the crimes start up again, the city's leaders command Bryce to help investigate.
They assign an enslaved fallen angel, Hunt Athalar, to make sure she does. But as Bryce fights to uncover the truth - and resist her attraction to the brooding angel who shadows her every step - she finds herself following a trail that leads deep into her own dark past.
