Several people have asked me whether the book Harry Potter and Torah is for children. The answer is no, it's written for adults or teenagers.
As you can see from the sample chapter on the web site, the book is a collection of fairly sophisticated Jewish insights. Yes, they're based on themes from the Harry Potter series. Yes, the ideas in the book can be made interesting for children. But this book was written with young adults in mind.
Also, while the book was written to be interesting for people with little or no Jewish background, my experience is that it's also very interesting for those with a background in Jewish scholarship. People with less background can ignore the sources and footnotes, and people who want to can look at the sources and footnotes.
