Trajectory and operations
Lagrange points, halo orbits, and the cost of staying put
L2 becomes much more interesting the moment you stop treating it like a parking spot.

Why this name, why this book
I wanted more hard science fiction where competence actually matters on the page. Not the glossy version. Not fake authority. Just somebody tired, technically serious, and still able to do the next thing right.
Long-distance running sharpened that taste. You learn pretty quickly that drama is overrated. Pacing matters. Restraint matters. What you can still do when you are tired matters. That is the kind of resilience I wanted in the book.
The person behind the pen name comes out of a long stretch in software, with engineering degrees, too many languages, and the habits that go with that. I like systems that stay legible under pressure. I am comfortable close to the machine. Opening a hex editor to figure something out does not feel exotic to me. It feels normal.
Kai Wrenbury gives me a place to write in that register. The site keeps the lines clear: the book is fiction, the research is public, and the interesting part lives in the tension between what is known, what is plausible, and what a story can get away with.
