The Ursa Mirage is now an audiobook

D.T. Rivellore — Wed, 02 Sep 2026 00:00:00 GMT

Dear reader/listener,

The Ursa Mirage can now be heard. The audiobook just went live on Apple Books, clocking in at eight hours and thirteen minutes from the high mesa to the last page.

My hope is that this makes the story accessible to anyone who loves books but lacks the time to sit with paper—whether you are tackling a long daily commute, out on an evening walk with the dog, or simply washing dishes after a day that took everything you had. I know those routines well; I live in them most days myself.

There is also something fitting about hearing it aloud. The entire novel turns on listening—to machines, to faint echoes, to a signal that refuses to die. Letting that voice ride along with you at fifty miles an hour isn’t a secondary experience. It might be the closest you can get.

As always, a gentle favor: if you take the ride with Sarah, please leave an honest review on Goodreads. Debut novels survive on those quiet recommendations, helping the next listener take a chance on an eight-hour journey.

Thank you for your time, your kindness, and your ears.

The Ursa Mirage is now on Apple Books

D.T. Rivellore — Tue, 01 Sep 2026 00:00:00 GMT

A brief, happy update today: The Ursa Mirage has officially arrived on Apple Books.

Up until now, the novel has lived solely in paperback and on Kindle via Amazon. While that reaches many wonderful readers, I know just as many of you prefer reading directly within the Apple ecosystem on an iPhone, iPad, or Mac—without having to juggle separate apps. If that sounds like you, this edition was made with your reading comfort in mind. It is the exact same story and text, simply resting on a brand-new digital shelf.

The link is storefront-neutral, so clicking through will automatically take you to your local country’s Apple Books store. I have also refreshed the site so you can easily browse all three editions side by side on the book’s main page.

As always, a quiet and heartfelt note: if you take this journey with Sarah and reach the final page, leaving an honest rating or review on Goodreads makes an immense difference. For a debut novel, your thoughts and stars are genuinely what help the story travel across the dark to find its next reader.

Thank you so very much, as ever, for your time, your kindness, and for reading.

The Ursa Mirage Giveaway — Thank you!

D.T. Rivellore — Tue, 11 Aug 2026 00:00:00 GMT

Hi!

I just wanted to take a moment to say a genuine thank you to everyone who entered the giveaway for The Ursa Mirage.

Seeing over 1,000 of you enter and nearly as many add the book to your shelves, was completely overwhelming in the best way possible. When you put a story out into the world, especially a dense, high-concept sci-fi book you’ve poured months of work into, you always wonder if it will find its audience. Seeing this kind of response means more than I can say. The book is in its lowest price possible on Amazon in case you are interested.

To the 100 winners: your copies should already be sitting in your Kindle libraries! I hope you enjoy the trip into the story, and if you have a spare minute when you finish, dropping an honest rating or review on Goodreads would mean the world to me.

To everyone who didn’t win, thank you for stopping by and checking out the book. If you decide to pick up a copy on Amazon down the road, I hope it keeps you hooked.

Thank you all for making this release so special.

Cosmic Scale: Why Space-Time Is the Ultimate Mystery

D.T. Rivellore — Wed, 15 Jul 2026 00:00:00 GMT

One of the most mind-bending aspects of theoretical cosmology is how light, distance, and gravity interact over immense scales. From gravitational lensing to atmospheric refraction, the universe is full of phenomena that challenge what we think we are seeing.

The title of The Ursa Mirage hints at that exact tension — the line between physical reality, theoretical observation, and the vast scale of the cosmos.

Writing hard science fiction means respecting the intelligence of the reader. It means ensuring that when complex theoretical concepts appear, they are treated with mathematical and logical discipline rather than fantasy hand-waving.

To everyone currently reading or keeping it on their shelves: thank you for being an audience that appreciates high-concept, intellectually demanding sci-fi.

Spooky Action at a Distance: The Strange World of Quantum Entanglement

D.T. Rivellore — Wed, 18 Mar 2026 00:00:00 GMT

In 1935, Albert Einstein, Boris Podolsky, and Nathan Rosen published a paper highlighting a phenomenon that Einstein famously dismissed as “spooky action at a distance.” Today, we know it as quantum entanglement.

At its core, entanglement describes a state where two particles become inextricably linked. Measure a property of one particle — like its spin or polarization — and you instantly know the corresponding property of its pair, regardless of whether they are separated by a few millimeters or a billion light-years.

What makes this so mind-bending to natural philosophy is what it implies about locality and observation:

The Interconnectedness: Entangled states suggest that physical information isn’t strictly confined to isolated local regions in space-time.
The Measurement Problem: The universe seems to refrain from defining certain properties of a system until an observation actively forces a collapse into a definitive state.

It is precisely these theoretical edge-cases — where the fundamental laws of reality challenge human intuition — that make quantum mechanics such a rich playground for speculative thought. When science reaches the boundaries of what can be directly observed, it naturally sparks the imagination.

The Ursa Mirage is where I took that imagination for a walk: a hidden city on a New Mexico mesa, an impossible correlation between distant particles, and the ten years it takes for the equations to sing. You can read it on Amazon, or add it to your shelf on Goodreads.
