It's safe to say that Harry Potter and the Cursed Child is everywhere. With Scholastic announcing Wednesday that more than 3.3 million copies of the book have already been sold, it's clear that the HP fandom is alive and well. If you've yet to revisit the magical trio and their offspring, maybe this will help. Amazon Kindle has released a list of the top ten quotes from the book most highlighted by its users, as Entertainment Weekly reports.Themes of friendship, love, and responsibility are through lines in both these quotes and the many books that preceded them. Fans of the franchise seem to hold these up as its defining tenants. The third most popular of the lines, "Those that we love never truly leave us, Harry. There are things that death cannot touch," in addition to being lovely, is very similar to sentiments spelled out in previous Potter installments.The two-part play, and the premiere production currently running on the West End, have received good reviews for the most part. Like any other media with an active fan base, Cursed Child has been criticized for a couple of supposed slights , but that's certainly not stopping anyone from indulging in the magic.
