This series is suitable for reluctant readers, but the content is obnoxious. The main character, Horrid Henry, is badly behaved, mean, and disrespectful. He bullies his younger sibling, Perfect Peter, who is the complete opposite of Henry. I would discourage kids who can be easily influenced into behaving a certain way from reading these books. However, they did work well to get my brother out of a slump where he had stopped reading. The content is slightly like the Diary of a Wimpy Kid.
