Jim Mercer is a man with an unhealthy obsession with a woman he’s never met. The psychology of the character either shows a troubling lack of understanding of what it means to have a healthy relationship with a woman on the part of the author or a masterful look into the psyche of a terribly flawed character. This could have been so much better if the author had made the character into something more intelligent, both mentally and emotionally. Decent time travel story for the most part, although a lot of things are hand waved and that can take you out of the story.
