The Concubine and Her Vampires - The Covenant of New Orleans, #1

When destiny becomes reality. Born a blood demon, Olivia Martin's sole purpose is to become a blood slave to a vampire. She is nothing more than a blood bag. With a vampire as her master, she would want for nothing, her every need and whim catered to, but becoming a prisoner was not the life Olivia would have chosen for herself. At least, until she met Jared and his four brothers-at-arms. Giving yourself to one person was easy.
Having fun with two, exciting. But a harem of lovers? It was more than Olivia ever considered possible. Need, lust, and blood drive Olivia to find a strength inside herself to not only accept her five sexy-as-sin vampires, but to also protect herself from an evil hell bent on claiming her for its own.
