If you're anything like me, you'll hate not knowing a bit about a book before buying it, and there's no "blurb" here, so here's the back cover copy to give you a helping hand:
"Harper Blaine was slogging along as a small-time PI when a two-bit perp's savage assault left her dead.
For two minutes, to be precise.
When Harper comes to in the hospital, she begins to feel a bit...strange. She sees things that can only be described as weird - shapes emerging from a foggy grey mist, snarling teeth, creatures roaring.
But Harper's not crazy. Her "death" has made her a Greywalker - able to move between our world and the mysterious crossover zone where things that go bump in the night exist. And her new gift (or curse) is about to drag her into that world of vampires and ghosts, magic and witches, necromancers and sinister artifacts...
Whether she likes it or not."
Now whether teeth can "snarl" or not I'll leave up to you to decide but it's not really as exciting as the blurb makes it sound. It's pretty creepy, and atmospheric, but action-packed opener aside (when Harper is beaten to death), it's slow going. It's more PI type stuff in a fantasy setting, than vice-versa, which isn't really my thing, so if you're a crime novel buff with a thing for a bit of fantasy on the side this may be right up your alley.
