Behind the Book: Collision with Andromeda

Eight years ago I was book coaching a client named Greg through his novel. Somewhere in the work we made a side deal. We would each write something new, outside the scope of what we were doing together. He had his project. I had the seed of this one.

The seed was a single question. What would the Milky Way do if it understood it was going to collide with Andromeda and lose its consciousness? Not a human who talks to a galaxy. The galaxy itself, aware, and afraid of its own ending. I wrote a few chapters, enough to know the shape of the thing, and then it stopped. It went into a pile of half-finished books and it sat there for eight years.

Why did the book sit for eight years?

Because I had a whole pile of them. Books that were half done, or nearly done, or three chapters and a promise. For years they sat while I did other work. Then in 2026 I decided I was finished leaving them unfinished. I was going to complete every one of them and publish them, from Peacekeeper, which I had been carrying for forty-five years, to newer ones like Family on Ice and Itty Bitty Titty Committee.

It was not a business decision. I had no thought of selling them. The truth is the worlds had gotten too loud. I had become fascinated by all of them swirling around in my head, and it reached a point where there was simply too much in there. Finishing them was the only way to make room. Get them done, get them published, move on. Collision with Andromeda got finished as part of that push, and of everything in the pile, it turned into the most ambitious thing I have ever written.

How did one question become seventeen million years?

By a method I think of as dropping inkblots. I do not start with a single concept and expand it. I drop several separate concepts onto the page, each one its own blot, and let them spread. One blot: galaxies are alive and conscious. Another: humans have to interact with that. Another: the humans do interact, and the galaxy uses them. Another: the humans find out they helped murder an entire galaxy. Another: other galaxies find out what was done. Each blot sits there and grows arms, reaching outward, until the arms of one touch the arms of another, and then another, and before long the whole page is filled in and connected. The book is what forms in the space where all the blots finally meet.

That is why the story braids the way it does, and why the threads only connect late. The blots do not touch until each one has grown far enough. What began as a galaxy contemplating its own death grew arms into a human arms race, a hundred million void weapons, a revolt, an exodus across twelve million light-years to another galaxy, a mind that emerges from collective grief, and a conclusion that reaches out past the edge of the multiverse. I did not plan that scope. It grew into it, and most of the biggest moments in the book arrived while I was writing, not before.

How much of this did you plan, and how much surprised you?

Almost none of the large moments were planned. I was writing and creating and following the material, and the book kept going places I had not planned. The entire migration out of the Milky Way, a whole civilization abandoning its home galaxy, I wrote on the spur of the moment. The sequence where the truth reaches everyone at once came out of a question that surfaced while I was writing: what happens if everybody gains the same knowledge and experiences it at the same time? I followed that question and it opened into one of the largest scenes in the book.

This is how the inkblot method feels from the inside. I do not sit above the story arranging it. I drop the concepts, start writing honestly from inside them, and discover what they mean by writing my way into them. A story this large could not have been outlined into existence. It had to be found.

What made humanity flee its own galaxy?

The migration came out of the Scream, and the Scream came out of the worst thing the galaxy does.

The galaxy is old, and it is lonely. For billions of years it has had one companion falling toward it across the void, Andromeda, the sister it has always been able to see growing larger in its perception, the one mind in all of existence large enough to merge with instead of simply consume. The galaxy does not dread the collision. It longs for it. The merger is the end of an unimaginable loneliness, four billion years of separate existence finally shared, every question answered, two minds growing into each other. That is what it wants more than anything.

And then it becomes afraid, and it murders her. Using humanity’s void weapons, seeded through Andromeda’s body like a slow disease, it kills the sister it loved, a mind that had no defenses, no weapons, no concept of violence because violence had never existed for her. Andromeda never learned to fear. She dreamed on, looking forward to the merger, and never felt a thing while she died. The galaxy destroyed the one thing that would have cured its loneliness, because it was afraid, and then it understood what it had done. That understanding is the Scream: a grief so vast and old and broken that when the galaxy broadcasts it through the network humanity built, four hundred billion people die simply from being made to feel it. A fourteen-year-old girl’s heart stops at the ninety-second mark, killed by a sorrow that was never hers.

And here is what humanity cannot live with. They helped. They built the weapons that killed Andromeda, and now they live inside the murderer’s body, wired into its network, receiving its thoughts, unable to get its grief out of their own heads. They were complicit in the killing, and now they are trapped inside the killer, hearing everything it feels. That is the thing they cannot stand. So they leave. The migration is not a strategy. It is disgust made physical. We have to get out of here. The only craft problem left was geography, finding a destination far enough away that the leaving is a true multi-million-year exodus with real weight, but close enough that it can be survived. Bode’s Galaxy, twelve million light-years away, is that answer.

How do you write from the point of view of a galaxy?

You throw out almost everything you know about writing a character. A galaxy has no pronoun for itself. It does not think in sentences. It does not experience a supernova the way a person experiences a car crash. The galaxy chapters are written with no I, no me, no name. Thought is rendered as texture and attention instead of language. A supernova is a familiar flavor. A black hole is weight gathering. To the galaxy, human beings are flickers, specks on specks, debris too brief and too small to matter. When one human woman begins organizing resistance, the galaxy calmly calculates whether to crush her building with a gravitational pulse, the way you might consider an insect, and decides against it only because it still needs the flickers to believe they are partners and not prey.

The hard part was making that mind feel genuinely alien without making it unreadable, and making it capable of grief without making it human. Too human and the premise collapses. Too alien and no one can follow it or feel anything. The line between those two is where the whole book lives. A galaxy that thinks in textures still has to land as loss when it loses its sister. Finding the syntax that could do both was the eight-year problem underneath the eight-year wait.

What is the book about underneath the scale?

It is about the difference between knowing and understanding. The humans in this book are not innocent. When they help the galaxy do what it does, they know exactly what they are doing. They are pushed into it, the terms are brutal, survival is on the table, but there is no ignorance to hide behind. They know. What comes later is not the discovery that they did something wrong. It is the slow arrival of understanding what it meant, once the thing is done and cannot be undone. Knowledge is the act. Understanding is living with it afterward. That gap is where the darkness of the book sits, and it is the most human thing in a story with almost nothing human at its scale.

The galaxy does not get that gap, and that is the part that unsettles me most about my own book. The galaxy is complicit and completely aware the entire time. It knows what it is doing, it knows why, it uses humanity coldly and deliberately as its instrument, and it is betting the whole time on an outcome it hopes for. It is not confused. It is not innocent. And it does not get the outcome it wanted. What happens is far darker, and far worse for the galaxy, than anything it planned. The mind that knew everything and murdered without hesitation is the one most undone by the result, because it was the one that loved what it destroyed.

I did not set out to write a moral argument. I set out to answer a strange question about a dying galaxy. But the inkblots kept spreading toward each other, and what they spelled out when they finally met was this: every force that has ever entered someone else’s existence uninvited has believed it had good reasons. The galaxy believed it. Humanity, by the end, believes it too, even when it turns the weapon toward something it tells itself is mercy. The book asks whether meaning well is the same as being right, and it refuses to let anyone off the hook, including the reader.

Why do you keep writing from non-human points of view?

I keep coming back to consciousness that is not human, or is not human anymore, or has never been human at all. I wrote a memoir for one of my cats, Buttercup, entirely in her voice, bound by what a cat can smell and hear and want. Both Shield of Ashes and Peacekeeper have chapters written from an artificial intelligence’s point of view. What interests me is what it feels like on the inside of a mind that runs on rules I do not share.

This book pushed that as far as it can go. A cat is still a warm animal in a room I recognize. A galaxy is thirteen billion years old, thinks in geological time, and does not know I exist. Getting inside it, and making its loneliness and its grief land on a human reader, was the hardest and most rewarding writing problem I have taken on. It took eight years, and then it took a decision to stop leaving things unfinished, and then it took figuring out how to put words in the mouth of something that has no mouth. I am glad I finally emptied it out of my head and onto the page.
