The writing in this book was absolutely horrible. Concepts that were really central to the plot like mental health, suicide, and many worlds theory were so poorly researched that often things were shared about them that were blatantly false and uneducated. The characterization of all of the characters was incredibly poor, and each character was so shallow in their emotions and dialogue that it was painful to read. This was one of those books where it was simply so bad that it was funny, and laughing at how poorly it was written was the only reason I even finished it. Unfortunately, I don't understand the hype that this book has had the last few years.
