Brandon announced yesterday that he will be doing a live reading and Q&A this Saturday, September 1st, at 6:00PM PDT for Read for Pixels 2018. Just follow this link to join the livestream on Youtube when the time comes, and if you log into YouTube you should see a chatbox to participate in the Q&A. Questions will be selected by a moderator. There's no news yet on what he will be reading, but Legion or Skyward are safe bets!
You can pre-order a signed hardcover copy of Legion: The Many Lives of Stephen Leeds, releasing on September 18th, from Barnes & Noble at no additional charge. This collection includes the full trilogy of novellas, including the original Legion, Legion: Skin Deep, and, new with this release, Legion: Lies of the Beholder. If you've never delved outside the Cosmere, Legion is a great place to start--especially with the story now complete!
