There are many great reasons to visit Sonoma County, but for Bay Area book lovers, the Sonoma County Book Festival on September 25th is a really great reason. This year, Commonwealth Club members and friends will be pleased to see author Yiyun Li at the event. Li won a gold medal in this year's California Book Awards for her novel The Vagrants.

Learn more about the book festival, which is free to the public.
