The Prince of Egypt Brothers in Egypt

I read the book, "The Prince of Egypt Brothers in Egypt".

First, the prince of Egypt brothers in Egypt was naughty, but they change gradually through various experiences.

But it was difficult for me to read this book which is PGR3..

So, I skip parts that I didn't understand and consulted a dictionary. It took time to finish reading..

And so, I want to read books which level is PGR1 or 2 next time.
