A limited number of VIP meet and greet packages with the former first lady will also be available.
"I couldn't be more excited to visit even more cities across the country and around the world," Obama said. "I've been so humbled by the response to the tour thus far and the overwhelming interest we've received from so many communities we weren't able to visit this year. That's why I'm thrilled that we're able to expand our conversations to these new settings and wider audiences. I can't wait to continue the discussions that have been so meaningful for me and, I hope, for so many others."
Sales for her book topped more than 725,000, just days after its release.
