Bests & Worsts Reviews from Amazon

The book had mostly positive reviews (???) I received the book yesterday; while browsing, I read that " Menelaus was King of Sparta who married a princess from city of Argos, a city which lay north of his own , Helen" Menelaus was the younger son of Atreus, king of Mycenae and he became King of Sparta , by marrying Helen, daughter of Zeus and Leda, the wife of the Spartan king Tyndareus. I do not believe that somebody who writes this, is qualified to write a book about the ancient history. I am also curious about the qualifications of the editor. I am returning the book Very disappointed
