After more than a decade of "Harry Potter" films, we should all be experts when it comes to J.K. Rowling's wizarding world.

But how much do you actually know? Are you a whiz like Hermione? Or keenly observant like Rita Skeeter?

Well, before you dash off to the final movie opening this week, "Harry Potter and the Deathly Hallows: Part 2," pull out your pensieve or dust off your Potter books and let's see if you pass these "Muggle-fied" O.W.L.s.

1. What kind of dragon did Harry fight in his fourth year?

2.

I entered the glass marvel of the Salt Lake City Library and made my way toward a table piled high with colorfully covered novels.

People mingled in a line with books piled high in their arms. They were there for the Breathless Reads Book Tour that featured five bestselling young adult authors from across the country: Utah author Ally Condie, who wrote the recently published "Matched" (Dutton Books, 2010); Andrea Cremer, author of "Nightshade" (Philomel, 2010); Brenna Yovanoff, author of "The Replacement" (Razorbill, 2010); Beth Revis, author of "Across the Universe" (Razorbill, $17.99) and Kirsten Miller, author of "The Eternal Ones" (Razorbill, 2010).

I can still remember the day when we moved to Idaho and my parents had to use walkie-talkies to communicate between vehicles. I can also remember the first time I ever saw a movie on DVD -- you mean you don't have to rewind? You can actually click on screen icons like a computer? Wow!

And I clearly remember a conversation with my mom in which she prophesied a future TV that would act as both a television and computer, and it would be completely flat, like a picture on the wall. I didn't believe her. We still had to get offline then to make a phone call. I used floppy disks in elementary school. Only a few years ago, I remember reading in a magazine about the prediction of the iPhone. An iPod that could call people? Impossible.

I like to think that I was the first one to discover "The Hunger Games." I mean, I didn't catch on to "Harry Potter" until after the fourth one was released. I hadn't even heard of "Twilight" until after "Eclipse" was in bookstores.

Take a peek into my bedroom, and you will see many books. Of these, one entire shelf is written by me, 12 books of varying styles and sizes. The first one, from when I was 6, is merely a stack of white computer paper punched with holes and tied with string.

Your heart drops into your shoes and works ferociously as it pumps blood from your toes to your hairline. You can feel your neck and cheeks get hot and an alarm sounds in your brain. Everything begins to shut down. You splutter. Tears squeeze out of nowhere. You want to run away.
