Nothing But Blackened Teeth

This wasn't exactly what I expected, but it wasn't bad. This book is very short, so there are going to be some things that feel like they are missing. In this case, it felt like some character development was missing. However, the lack of character development made it easier for me to put myself in the character's place. And that might have been the point.
The horror parts are very creepy and are the strength of the novella. Knowing a little bit about Japanese folklore would increase your enjoyment and the creepiness of the book. There are definitely scenes that I will remember long after reading the book.
If you are looking for a creepy urban legend type book, this will be a book that you will enjoy.
