I think maybe this book wasn't my thing!
I enjoyed a lot of the story telling but was confused by several points. There were a lot of plot holes and inconsistencies.

How did he touch blood, and think it was a "different wetness" and not at all notice the blood on his hands? Where did it go?

Maybe I'm also not a fan of the unreliable narrator style, but the plot twist was jarring. There was no foreshadowing that I noticed. It seemed to be just thrown in for the sake of a plot twist without any real forethought.

I did like the writing style, and it was an engaging and addictive read despite what I didn't like about it.
