Dark Matter began here. Today, it becomes a book.

From Substack serial to published book

Today, Dark Matter becomes a book.

This story began here on Substack. One chapter at a time. One conversation at a time. It grew because people stayed with it. Reading, listening, commenting, and thinking alongside me long before it was anything more than an idea unfolding in public.

That matters deeply to me. Dark Matter was a Substack-first story in the fullest sense. It became what it is through a community of readers and writers who cared enough to keep showing up.

Today marks a new step. Dark Matter is now live on Amazon as a Kindle book, with paperback, hardcover, and audiobook editions coming over the next few weeks. This isn’t a reinvention of the story. It’s an expansion into new formats, new spaces, and beyond this platform.

If you’ve already read or listened to Dark Matter here, one of the most meaningful ways to support this next phase is simply to leave a review on Amazon. And if you’d like to experience the full story as a finished book, it’s now available in a format many people enjoy for reading fiction.

However you choose to engage, or even if you just take a moment to mark this milestone with me, thank you. I’m proud of what this story has become, and proud of the fact that it grew here first.

This is the moment where Dark Matter starts reaching further. And I’m very glad you’ve been part of the journey so far.

Warmly,
