I just heard back from one of the publishers I'm looking into! They're interested in looking at publishing an adapted version of Dreams in Darkness as a novel. The potential advance is... it's absolutely stellar. They want me to write up a summary of how I'd expand the story to fill a full novel, and then they also want a chapter or two before they officially pull the trigger.
I've never been this freaking excited before in my life! I'm not only doing what I love, but I'm potentially bringing Slender Man to a wider audience. And I'm making money doing it. Holy shit. It's just... too much for me to take in right now. Just way too much.
