Oblivious - A Kendra Spark Novel, #4

Kendra communicates with ghosts. She's gone from a best-selling suspense-mystery author to an FBI asset on a secret mission team. Jenna, an FBI criminal analyst and Kendra's best friend, died in a fatal accident, but she continues to work for the team with Kendra's translations. Derek Knight, an FBI Special Agent, leads the FBI-Violent Crimes Unit-Sensitive (better known as Supernatural) Investigations team to fight evil entities disrupting the Earth plane. A Voodoo Priestess turned evil witch of the dark arts steps in with a vengeance. The world changes for Derek now that he sees the dark spirits.
But defeating them is no simple task, especially when one resides inside someone on his team. Oblivious much?
