It took me a little time to get into this book. For a story that starts with a woman being abducted and sexually assaulted (not graphically) by a serial killer, it had a weird lighthearted tone. That tone mainly holds up throughout the book, even when things get more dire, By the end I decided I liked the balance. It worked well, and it was kind of nice that the story wasn't bogged down with terror and dread despite everything that's happening. If you suspend your disbelief on the apparent supernatural abilities of the killer (and the vigilante) it's a fun, quick read despite the dark subject matter.
