I really liked this author's Owl series, so I was looking forward to this book, the debut of a new series. Unfortunately, I found I didn't connect with the main character and first-person narrator, Kincaid Strange. More than just a badass heroine, she seems to have a great deal of hostility and shows it at least from time to time in her interactions with everyone--and a lot of her problems in this adventure could have been reduced if she could just have gotten over herself and simply communicated with people who were ready to help out.
Granted, she is in a tough place. She's a voodoo practitioner in an alternate Seattle, on the outs with her mentor Max (a much more powerful voodoo practitioner) and her ex-lover Aaron, a police detective. She worked for the police department raising corpses as "four-line" zombies to help investigators until a new chief of police banned everything to do with the paranormal and put her out of a job. Now she just manages to get by via seances with her roommate Nate (my favorite character--he's a lot of fun and really a true friend to Kincaid if she could only see that)--Nate is the ghost of a grunge musician who died in the 1990s, and he lets her "bring him back" onstage to perform for college groups.
Kincaid calls Nate by writing on any mirror (or other reflective surface) in lip liner, and he materializes partly or wholly in response, but as you've gathered from what I've said, she's not very nice even to him, a lot of the time. Still, scenes with Nate were the most fun for me in the book. Other ghosts appear, and one of them is a powerful sorceror's ghost from long ago named Gideon. I thought his character was well developed--and very ambiguous between ally and adversary to Kincaid.
Kincaid becomes a temporary caretaker for a unique zombie named Cameron, who has just died and been raised but has no memory of it. He's not just a dangerous "five-line" zombie--the lines of "Otherside" that reanimate a corpse are much more complicated in him. Yet he's a rather nice fellow, an artist who just wants to complete his work, and Kincaid must try to prevent the ferocious zombie nature from coming out in him until she can return him to her mentor (whom she has problems with, remember).
So, trying to find out how Cameron died and who raised him, Kincaid gets entangled in a series of murders involving some very dark forces--and ghouls, poltergeists, etc. The adventure gets quite intense, and more than once Kincaid barely survives. There's a secret underground city populated by zombies and other paranormal beings, and there are constant intrusions in the story from Otherside, which seems to be a dimension, an essence, energy, and more, all at once.
Here was my other problem with this book--I was never able to visualize those scenes with Otherside clearly. To do any of the paranormal things she does, Kincaid has to "pull up a globe" first, and it always takes a lot out of her to do that and to maintain it. Once she's finished what she's doing with Otherside, she "lets the globe fall." Sometimes she has to go through several globes in the same day, until she can't raise any more of them. I'm still puzzled at what a "globe" is or what it would look like in any of the action scenes.
It's an exciting adventure, full of suspense and danger, and an actual mystery with a mildly surprising solution. And if my caveats don't put you off, you may enjoy it much more than I did!
