On Saturday, Seattle area readers are celebrating Independent Bookstore Day. There’s the Passport Challenge -- an attempt to visit all 29 participating bookstores in the Puget Sound Region, and get a stamp from each one. We talk with Tom Nissley, owner of Phinney Books about why Seattle's independent bookstores continue to thrive. We can only make Seattle Now because listeners support us. Tap here to make a gift and keep Seattle Now in your feed. Got questions about local news or story ideas to share? We want to hear from you! Email us at seattlenow@kuow.org, leave us a voicemail at (206) 616-6746 or leave us feedback online.See omnystudio.com/listener for privacy information.
