Dd7 has only recently been able to cope with HH because she was horrified by anything that involved blood, executions etc. Now she is OBSESSED. She is at this minute, watching the HH songs on YouTube and has 20 odd HH book sitting beside her bed (from the library). She is, however, a newly minted history nut. A family friend who is high school history teacher, examiner and has PhD in history loves the series - he'd agree it's very much oversimplified but thinks a great intro for kids.
