I read the book Paper Towns by John Green as a teen, and out started out good, then just kept getting better and better and way more adrenaline inducing. The characters were going on this crazy exciting midnight excursion and I was up reading until like midnight.
At a certain point, the mood just dropped straight off of a cliff. It was so depressing and draining but I was in too deep at that point, so I kept reading. After like two chapters of emotional torture, I knew I had to stop so I stopped reading and fully deleted the book off of my kobo and went to sleep.
The next morning though, I woke up desperate to know what happened, so I booted up my computer, went through Adobe's proprietary mess of a program to redownload the book onto my kobo, skipped the entire middle section, and kept reading. In the end, the ending was okay, but definitely not worth that rollercoaster of emotions.
I read John Green's The Fault in Our Stars right after, and I enjoyed it!
