Temple of the Inner Flame - Rest in Power Necromancy, #1

A New Age cult. A paranormal killing. How can a necromancer defeat an enemy that's already claimed her soul? "A human body should burn red-yellow or orange. But these flames were bright cobalt blue. All flame. No smoke." Necromancer Kezia Bernard sees her ability as both a blessing and curse. While it's an honor to connect the African diaspora to their deceased ancestors and channel magic from the past, her power is overshadowed by a crushing affliction.
One that cost her a career as a scientist and the family she loves more than life.  When a millionaire cultist mysteriously burns to death by supernatural fire, it's up to necromancer Kezia Bernard to investigate the source of this brutal magic. Armed with the ancestral gifts of preternatural senses, Kezia vows to uncover the nemesis incinerating the cult's members. But when the villain she's hunting brands her with the same scorching magic, she knows her time is running out.
If she can't destroy the source of the fire smoldering within her, even the powerful protection of her ancestors won't save her from a twisted fate that ventures far beyond death... "... And so I shall possess you, my sweet! Consume your very soul. And drink you down and breathe you out and then we both shall sleep." Whip-smart and darkly mystical with page-turning twists, the Rest in Power Necromancy trilogy is a complete, spellbinding urban fantasy & paranormal mystery series for fans of K.
