Main title is trash honestly, the sub-title is more accurate to the story which is actually really good. It sets a dark tone early on and with very few exceptions it maintains it (up to chapter 28 at the time of this post).
The plot raises a lot of questions that at the moment are left unanswered but the clues given through the writing lets you draw your own conclussions and most of the time they end up being correct, which I consider a good thing. It means that the author can convey his intention with mere clues.
Well worth a read.
