First, remember that nothing is set in stone; this schedule will PROBABLY not change, but that doesn’t mean you should burn down a windmill if it does.
With that caveat, I’m pleased to announce that Tor has ‘finalized’ a release schedule for the Serial Killer books:
I Am Not a Serial Killer: April 2010 (which, in practice, means March 30)
Mr. Monster: October 2010
Full of Holes: April 2011
They will be released as trade paperbacks, about 6 months apart, with a “significant investment” in bookstore displays and such. I’m incredibly excited. Releasing the books on an accelerated schedule like this will build a lot of momentum, and we should be able to generate a lot of excitement. I’m starting to work on a book tour for this spring, so if you live near (or work in) a bookstore you’d like me to visit, please let me know!
