★★★★☆ Rated 4.6 out of 5 by early readers on Amazon and Goodreads.

Last week, Dark Matter crossed an important threshold.

It became a book.

That moment mattered. But it was still a digital one. A Kindle edition, living on screens, much like the story always had.

This week marks a different kind of step.

For the first time, this story exists as an object. Something you can hold, place on a shelf, lend, or gift. A physical form that changes how it moves through the world.

In the days following the Kindle launch, readers began leaving reviews across Amazon and Goodreads.

Since the Kindle launch, Dark Matter has received:
– 27 reviews on Amazon.com (4.5★)
– 4 reviews on Amazon.co.uk (4.7★)
– 14 reviews on Goodreads (4.8★)

I mention this not as a celebration, but because it marks a shift. The story no longer exists only between drafts and conversations. It has been read, assessed, questioned, and received by people who had no obligation to like it.

Dark Matter began here on Substack. One chapter at a time. One conversation at a time. It grew slowly and publicly, shaped by readers who stayed with it long before it became a finished book. Reading, listening, commenting, and thinking alongside me as the story unfolded.

Seeing it take physical form does not feel like a reinvention. It feels like a continuation. The same story, now anchored in paper.

If you have already read or listened to Dark Matter here, thank you. You were part of what made this possible. And if you would like to support this next phase, one of the most effective ways is simply to leave a review on Amazon. It genuinely helps the book reach new readers.

And if you feel like experiencing the story as a finished book, in print, it’s now there for you.

This is how Dark Matter starts reaching further.
Still rooted where it began.

Warmly,
