I started writing The Emotion Engine in March. It is September now, and I am only just writing the scene where Shaden finds the actual Emotion Engine.

The thing the whole book is named after.

Right now I am in Chapter 18, which is called Deliver. The document sits at 287 pages and 71,197 words, and I have about 2.5 chapters left to write. The epilogue has been finished for a while now, sitting at the end of the file like a destination I already know I am heading toward. I wrote it early and left it there on purpose. It helps to know where you are going.

The finish line is right there. I can see it.

Getting to this point required the story to change more than I expected. That is not unusual. An outline is a rough map, and the actual territory never matches a rough map perfectly once you are walking it. But The Emotion Engine wandered further from the original plan than either of my previous two books did. Characters made choices I did not plan for. Scenes that were supposed to be minor became load-bearing. Things I thought were central got quietly moved to the edges. By the time I was deep enough into the draft to see what the book actually was, the outline had mostly become a historical document.

What stayed: Shaden, the world, and the ending. Almost everything in between had to find its own shape.

Somewhere in the ruins, the tone leads Shaden to a door marked Engine Room.

And through all of it, the Emotion Engine itself stayed off the page. It was always there. The whole story points at it, pulls toward it, circles around it. But writing it -- putting it in a room that Shaden can actually walk into and stand in front of -- that did not happen until this week.

Writing toward an ending you already know is a strange kind of double vision. You are discovering the road while already standing at the destination. That sounds like it should be disorienting. In practice, it just means the destination stops feeling like a guess.

The machine. The thing the book is named after.

I am not going to say what the Engine does, or what finding it costs Shaden, because that is the whole last act of the novel. But I will say this: the version of it that ended up on the page is not the version I had in my head when I started. The changes the story made to get here changed the Engine too. It is better for it.

November 2026 is still the release date. At 2.5 chapters from the end, with the epilogue already written and waiting, that feels like a real date for the first time. Not a goal I am aiming at. A date I am walking toward.

I am having a good time.
