I read it up to a certain point. It was alright.
The protagonist, having been turned into a skeleton, apparently no longer has sexual desires. Yet the author/protag, makes plenty of references to how sexy or "stylish" his dark elf companion is.
I like when the author gives us thoughts of the protag, or maybe his outlook on things. In this regard, the protag is more similar to a mute, generic player character in an RPG, whose purpose in life is to silently tag along with the story plot and nods his head when asked a question.
The only two apparent motivators for the protag are the eros elf (over whom he apparently can't but still does lust over), and getting his flesh body back (probably partially relating back to the first point).
To be fair, there are some points I can appreciate; The setup of the countries is interesting, past events reflect themselves in future events (sometimes novels have apparent short term memory loss), there are some details of the skills and tactics used that give the world some life.
If faced with a binary [recommend]/[do not recommend], I would choose [do not recommend]. The world is interesting, but not enough so to overcome the thoroughly lackluster protagonist.
