I picked this book up last week at a homeschool convention. My oldest son is very interested in history and learning about the explorers. We have enjoyed books by this author before, so I felt like it was a good buy. I can't believe how blatantly anti-Christian the author is in this book. She makes Christians sound like the wart of the world! She makes it sound like the world progressed in knowledge and achievements in spite of Christianity. Although I am no history expert, some of her statements just didn't sit well with me, and I would really question whether what she wrote is fact or just her ignorant, prejudiced opinion. I will never purchase another book by her again.
