I'd think it would make it less valuable, my sister recently bought a book that was missing around 50 pages, and the store had to give her a refund.

CHAPTER 16
I did it Monday morning in my locker at school. I turned into a lizard.
A green anole, to be exact. It's a member of the iguana family. Like you care.
I waited till the bell rang for first period, which was English class. When everyone else was
out of the hallway, I just climbed into my locker. I tried to act cool about it, just in case
anyone was watching.
The locker was about two inches shorter than me, so I had to crouch. And it was so tight I
couldn't move. The only light was from the three small ventilation slits. I could hear my heart
pounding in the cramped, dark space. I was afraid.
