Thanks for adding LIVEWIRE VOODOO to your reading list.
It's got a lot of male characters, so reading your bio shocked me. Still, the book's wise "Obi Wan Kenobi" character Maddy is female medium who stands firm on moral principle, come hell or high-water. And the most reliable point-of-view character is Maddy's granddaughter, the 30-something Peg.
FYI -- LIVEWIRE started twenty years ago as a short story for an Ohio State creative writing class. Peg was POV, Maddy the "general" directing Peg, with Frank, the ghost, the only male providing comic relief. I got like a 99/100 on it (I had some typos). The short story's still there, but the backstory's fleshed-out. Which shifted the focus.
