When my novel Believers sold earlier in the year, the publication date was either going to be fall 2014 or spring 2015.
Well, there's been a decision, and it's... spring 2015.
Yes, the extra waiting will be hard (to quote my son: "Hasn't your book come out yet?"). On the other hand, there will be more time to generate prepublication interest among booksellers, reviewers, etc.
