I picked this one up somewhat reluctantly; my husband had found a copy for me, but then read it before I got to it and reported that he didn't care for it and could not recommend it. Still, I had asked for it, so I felt like I should give it a try. I have to admit I find myself a bit disappointed as well, though on different grounds. I'm going to disagree with his assessment that the book is well-written even if he doesn't like the subject matter. I found the quality to be lacking, regardless of how I felt about how negatively it portrayed humanity. And so it gets two stars from me, rather than the four he grudgingly awarded it.
The basic premise runs like this: Nanase works as a live-in maid. She can hear other people's thoughts. This book is composed of eight stories that tell of her employment in eight different households and what she overheard in each with her gift.
It sounded like such an interesting premise, but here's the thing. In order for it to be interesting, Nanase's ability has to add something to the narrative. This does happen in three of the tales, to varying degrees, but in the majority I felt like the psychic bits could have been taken out and the stories would not have suffered much. If you're going to make your main character presumably the only psychic in your fictional universe, you should use that, and the author does not do so nearly as much or as well as he could have. We are not given much information from Nanase's ability that could not have been conveyed just as easily, and in many cases more effectively, by other means. What she "overhears" in most situations does not appear to change her motivation or prompt her to act in any way that could not just as easily be attributed to or accomplished by completely mundane factors. Her ability plays no more of a crucial role in the events of most of the stories than does her height or her favorite color.
That does present an intriguing angle on the whole issue of what people hide, I suppose. It says that we are none of us as hidden as we think we are, that it doesn't take a telepath to see what we really are. Okay. I'll give it that much. Unfortunately, though, the way that is conveyed doesn't make for very compelling reading, and the repetition of the theme honestly gets a little boring. And yes, there are other ways in which what people hide and what they reveal are explored, but I didn't find that this was done all that effectively either. There is such a thing as being too subtle, and if I have to sit and search for a point to the whole thing rather than some sort of point suggesting itself, that's too subtle. I don't generally enjoy books in which the author hammers a message in too overtly, of course, but as a reader I also don't want to have to do all the work myself.
By contrast, though, a little more subtlety could have been used in description and conveying the characters' thoughts. The whole telepathy thing seems to have made the author a little lazy about exposition and character development. No need to show us the little signs of someone being nervous or aggressive or aroused or whatever when Nanase can simply pick it out of their mind and tell us about it, after all. No need for complex questions or mysteries about what's going on when she can read it straight from their thoughts. (Which, really, is what makes the first story so appealing to me, because it uses that and then turns the whole thing on its head -- but I run the risk of spoilers, here.)
And then the final story ("The Departed Mother") just completely lost me, when it should have been the most powerful. Nanase and the other three characters around whom it revolves are relatively believable, taking some unusual psychological factors into account. The reactions of the other characters read like a caricature, though, and I found the premise completely implausible. Some of that I can chalk up to cultural differences, maybe, but... It just completely shattered my suspension of disbelief.
When it comes right down to it, I enjoyed the first story, "The Plain of Emptiness", but felt that the rest of the book was unnecessary and not as well-done as it might have been. The author seems to have had this really neat idea, but then not really known how to use his chosen angle to its best effect. I won't completely recommend against it if you happen to have a chance to read it -- but it's fairly obscure and seems a bit difficult to find, and it's not something I'd go out of your way for. The idea had a lot of potential, but fell far short of fulfilling it.
