AG changed the description of the Girl of the Year 2018 event to this:

"3…2…1…all systems go to meet our 2018 Girl of the Year! Be the first to discover her exciting story of exploration at a special in-store event."

If you want to be like this girl, go to your local American Girl store to learn about the Girl of the Year on January 1! (And while your at it, watch the GMA reveal, too.)
