Review Detail of Lovemaker in Death Scripture

The novel is set in a brutal, dog eat dog world where everyone is looking out only for himself/herself, and loyalty and friendship is hard to come by. There are no heroes here, only people struggling to survive. This is a place where clans are wiped out, not by a superhuman character, but by putting paralyzing medicine in food and attacking sleeping people. The Main Character is out for revenge, but ends up being captured instead. Will he live and complete his revenge, or will his life will be like a flickering candle?
