I'd have to say that this is one of the best stories of this type that I've read. The whole "mind-control" or, for want of a better description, "mind intrusion" genre can easily get so unrealistic that the "suspension of disbelief" that forms the compact between author and reader is completely destroyed.
In this story, Levi Charon has managed to develop a plausible rationale for the protagonist's development of his abilities. And in addition to being plausible, there is enough of a storyline that it is reasonably easy to put yourself into the role adopted by the protagonist. One of the things that I particularly like about the the protagonist is his moral and ethical values which shape the way in which he responds to this talent that he is developing. In other stories of this genre that I've read, the old adage, "Power corrupts, and absolute power corrupts absolutely." seems to be the driver. But Chuck is concerned that he doesn't hurt the people on whom he "eavesdrops".
The love relationship with Carol is a bonus, and also very well described. Her actions and reactions are easily in the range of what might be reasonable for the situation. Oh, I nearly forgot to mention that some of the sex scenes are just plain hot. The ones with Carol are often in the category of, "Damn, wouldn't it be great if I could do that."
I've talked a lot about what's reasonable and logical. And while this is exactly what I mean, the point is that a realistic plot makes it a lot easier for the reader to become deeply involved in the story.
I've read several other stories by this author and he's on my personal "watch list" because he manages to say something and say it well in most of his stories.
Looking forward to seeing where this goes.
