Although my daughter Madison was too young to read when the first Harry Potter book was published in 1997, she and I made up for lost time in later years. We started out with my reading “The Sorcerer’s Stone” to her. With later books, as she grew up, we took turns reading them aloud together or listening to the audio versions on long trips in the car.

We have seen all the movies, but one stands out above the others: We were lucky enough to be invited to the New York City premiere of “Harry Potter and the Goblet of Fire” in 2005. An entire city block was cordoned off from traffic, and a red carpet rolled out in front of the Ziegfeld Theatre. The film’s three main stars, Daniel Radcliffe, Emma Watson and Rupert Grint, were there. It was special enough walking into the theatre on the same red carpet as the stars, but once inside, I think Madison went crazy when Radcliffe waved at her as he and the other actors walked in after we were seated.

It was a night I’ll never forget, but one that Madison remembers for quite a different reason: Although she, like millions of other girls her age, had a crush on Daniel Radcliffe at the time, she also got to meet an unknown actor who made his one Potter series appearance in Goblet of Fire. His name was Robert Pattinson. None of us could know that he would later go on to fame in the Twilight film series. I have a grainy cell phone photo of Madison with Pattinson from that night, and needless to say, my daughter, now a Twilight fan, has made good use of that photo.

Madison is 16 years old and completed the Potter series of books on her own. I also read the final book, Harry Potter and the Deathly Hallows, nonstop over the first weekend after it was released. It was a fitting conclusion to the series, but not an ending for me: My 8-year-old daughter Alexa is just getting started with Potter.
