It follows the motivations of different characters connected to one person(who is dead) and how those strings lead to their actions in their present situation. In short, Its an emotional yet an epic ride.Several conspiracies tying them together and how that is related to the main characters is certainly a treat to read.
The characters are the best suit of the series. Most of them are morally grey not to mention they are written extremly well.
The BL tag might be a turn of for some(it has a considerable number of male audience though) but that to serves as a plus point imo since the author uses the relationships themselves in a pretty intriguing manner.
