This was posted on King’s official board:
Steve will be doing a tour but at this point, I’m only aware of a US tour. We haven’t started working out the details yet.
The tour is to promote Under the Dome when it’s released in November but as you see there are no more details yet. So, please don’t bother the moderator by asking about it yet, I’m sure that when there are something new it will be posted on the site. I’ll publish the dates and locations in a future post.
I hope, I hope, I hope he comes out west and it is close enough for us to go together!
