J.K Rowling is the Antichrist and Amazon buys the Tales of Beedle the Bard

I haven't read the Harry Potter books but I've seen every movie. I don't have time to read 1000 page books but one J.K. Rowling book caught my interest recently. Apparently a book referenced in the last book "Tales of Beedle the Bard" was bought by Amazon.com for £1,950,000. The book is 157 pages and handwritten by Rowling herself. It contains five stories and is bound in Moroccan Leather
