The Kosters are a fun-loving family with nine children, ages 10 to 33. Seven children are still living at home. "Me and my children just love reading these books. The pre-requisite to come to the party is that you must have read all the Harry Potter books," explains Koster, who had seven books ordered of the latest in the series (book six) so that no one would have to wait to read it. While Koster talked about the party, preparations continued. Her husband was outside making wooden wands for party-goers. They had ordered wax molds and were creating chocolate frogs to wrap in golden foil. Koster herself was folding origami owls. The party would also be complete with a sorting hat, potions, and a magic mirror.
Koster maintains that they are not as much Harry Potter fans as they are reading fans, though she later admits they really do love Harry Potter. They simply love to read. The party is a way of extending their imagination of the book. Verlynn doesn't like the movies as much. "The movies distract from your own interpretations. Reading them is much better than watching the show," she says.
The party covers all ages. The Kosters have nine grandchildren that are also included in the event, four who live close enough to attend. "This is a good thing to have a party about. We include all the neighborhood friends and encourage them to read as well. Our object is to have fun! Instead of focusing on the frightening, we focus on the fun," smiles Koster.
