This isn't entirely bad, really, but I still only give it two stars. It has some potential, but in reality it just didn't command my attention. There's definite cultural differences, but rather than let me experience or understand them (such as in the Akitada books), it seems I'm expected to just accept them and move on without understanding something of the cultural the story takes place in. There's the potential for a good urban fantasy, but the pacing is off. It's not that it's too slow or not slow enough, it's that sometimes it's one and sometimes it's the other.
The story revolves around Detective Tokuda who investigates a strange attempted kidnapping, but we quickly learn that Tokuda's interest in this case goes beyond just a kidnapping -- the detective has history in the Naga river valley and his investigation slowly peels the layers of what's truly been happening here for decades.
I might read the following book, as it wasn't awful, but maybe not for just the moment. After all, it took me months to finally decide to finish this.
