The final chapter of former First Lady Michelle Obama's book tour will end with an appearance at the Ryman Auditorium.

Mrs. Obama released her memoir, Becoming, last month. The book has already sold more than 3 million copies. After an initial tour to 10 cities, Crown Publishing on Tuesday announced additional dates and cities.

“I couldn’t be more excited to visit even more cities across the country and around the world,” Mrs. Obama said in a news release on Crown Publishing's web site.  “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.”

Each stop will feature moderators who will appear in conversation with the former First Lady. Mrs. Obama's appearance at the Ryman will take place May 12.

Tickets for the Nashville event go on sale Friday to Ticketmaster verified fans and on Saturday to the general public.  Limited meet-and-greet packages will also be available.

A portion of tickets will be donated to schools, charities, community groups and other organizations.
