The event is Tuesday, February 5, at 5:30 p.m.
This is a ticketed event and will almost certainly sell out, so if your child is interested in attending, tickets should be obtained right away from the Access Books site. Click on this link: Jeff Kinney at Access Books
Mr. Kinney will conduct a writing demonstration and talk about the creative process. Pizza and cookies will be served, and there will be a raffle for Wimpy Kid books.
Do read the announcement carefully, if you plan to attend. Sounds to me like the event is primarily for children, and that parents accompanying their children will have to wait outside during the presentation.
What an awesome experience it would be to meet this author, especially for fans of the Wimpy Kid series--and double especially as the event benefits Access Books, which works to improve school libraries in needy communities.
