So one of the things you hear when you are submitting fiction, especially long-form fiction, is that lengthy response times are good. It means that the publisher is seriously considering your manuscript, that it has probably passed from the slush pile through the first readers and is perhaps, even right now as we speak, sitting on an editor’s desk awaiting the final stamp of approval before it is accepted.
Or it could just mean that your rejection letter was lost in the mail.
Night Watchman got rejected a lot before Hard Shell Word Factory finally picked it up. In fact, it’s probably my most-often-rejected book. It got rejected for being too scary; it got rejected for not being scary enough. It got rejected for being too weird; it got rejected for being too conventional. And sometimes it got rejected just because. But what else can you expect from a committee?
