It's like a show hole, just with books.
  1. You are sad that it's over
  2. Then you realize you can read the next book
  3. Then you remember the series is over
  4. You don't know what to do with your life
  5. You wonder why you even do this to yourself
  6. You say you won't read books anymore
  7. You reread parts of the book
  8. Someone tells you about a new book series
  9. You forget everything that just happened and fall in love with the new book
  10. Repeat
