I spotted this at Lilja's Library -- which is the all time best Stephen King website out there.
The moderator of King's board posted the following:
“I’ve heard back from Steve, who’s given me the okay to pass along the information he’d shared last week when I’d asked about book tours. He told me he will be going to France (and probably Germany) for a book tour so it’s not a matter of “if,” but rather a matter of “when.” I’ll post updates as they become available.” http://liljas-library.com/
Cool! I do wonder what wonderful story ideas he'll come back with.
