I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I'm working on children's books today and came across this. I haven't actually read it, just flipped through it, but dang some of those pictures! The scariest ones are probably the girl with the shark teeth, that kid on the cover with the rattlesnake fangs, the boy with the crocodile teeth, and the girl at the end with normal human teeth but the creepiest toothy smile ever.
