User blog:Gilderien/"Wikia" selling 14,381 books of Wikia content on Amazon

User:Wyvern Rex. noticed today that extremely confusing and contradictory books of "Inheriwiki" are being sold on Amazon, here. I then searched for books published by "Wikia" and found 14,381 books, sold for between £15 and £25. Is this really Wikia, or is it an impersonation?
