DC wrote a novel. It’s called The Boy Who Couldn’t Sleep And Never Had To. It’s going to be published by Broadway Books, a division of Random House. It should come out some time in the next year.
It’s being published as a “paperback original,” which means it will be immediately cheap and easy to carry around, instead of expensive and bulky.
For more of DC’s writings, you can check his personal website, dcpierson.com. There are short stories and things, and probably too many links to songs he’s into.
