Bests & Worsts Reviews from Amazon

My kids, age 7 and 8, loved the book. But the book lost most of its points because I lost confidence on the total correctness of the book as soon as I got to a place Ethiopia is depicted as Sunni Islam country. Someone didn’t do his research or got wrong information. Muslim population in Ethiopia are less than 30% of the total population. Ethiopia is a majority of Orthodox Christian and about 20% are Protestant Christian’s. As the neighboring countries were Muslim, the country was called island of Christianity. For this specific case I can correctly inform my kids, but I am really concerned about what else is wrong in this book. I bought around 8 books from DK, and my kids loved them all. But I am still concerned if they are getting fully correct education.
