Query: Do not order the books with the black cover

I am writing this as an avid fan and supporter of the Anastasia series, but please do not read the translation that is in the Black Covered books. The encoded language that Anastasia uses in the books has been distorted in these versions. If you want the true, authentic language order the books that have green covers. These black cover books are another method used by the powers that be to distort the truth and keep everything "in the dark."
