I'm writing this spoiler-free review now because last week, someone in my friends list posted a spoiler of how the book actually ended, and I found it hilarious, so thought I'd chime in. 
 I read Mud Vein YEARS ago. Back in... 2014. A friend told me that it was their best read of the year. 
 It was one of the first books that I DNFd. I stopped reading at 90%. So how did it get 1 star on a DNF at 90%? 
 The premise of the book was such fun that I HAD to keep reading to find out who did it and why. That part of the book was great. 
 It was also the LEAST satisfying conclusion to the question of "Who did it and why?" That could possibly have been imagined. That must have been an intense brainstorming session to figure out how to remove ALL impact from the book. Big congrats to the author and her team on that one. 
 Also, the protagonist. This book was a MASTERCLASS in how to write an unlikable, unsympathetic character. I liked nothing about them. 
 I put the book down as soon as found out who did it and why. 
 Great, interesting premise, let down by literally everything else in the world of writing.
