Of Blood And Passion by Pamela Palmer
"An amazing, action-packed series" NY Times bestselling author Kerrelyn Sparks
They call her the last sorceress: Quinn Lennox, the only hope of the vampires who are trapped in Vamp City watching their dark otherworld slowly die. But an ancient curse shackles the magic Quinn needs to save not only the vampires she's come to call friends, come to care for, come to love, but her beloved brother as well.
Arturo Mazza, the ruthless vampire who once betrayed Quinn, and has since waged a steady and relentless war upon her heart, vows to help her break the curse. But when the mission requires them to face Cristoff Gonzaga--the brutal and vicious vampire to whom Arturo once pledged undying fealty--Quinn must find a trust in Arturo that will test the very foundations of her soul.
