How many bad things can you think of to put your characters through? For a middle grade book, it's quite violent. But that is the only few flaws on the book. Yes, there are many misspellings and unfortunate decisions from Todd, the main character, but it's very understandable considering that he's a simple 12 years old kid. It's actually what makes the storytelling feels real, unique, and fresh, aside of the cool premise of the world he lives. Imagine, everyone can hear everyone!! That is a great premise that can open a lot of examinations: about privacy, communication, inner expression, and many more. It also makes a good first book, since it is open for huge character growth and exciting villain.
