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 books, the ones that will not annoy me with obvious mistakes. I have no need for big drama, I never enjoyed "fighting agains the big evil" stories. Needed something that's not boring, but gentle and mildly funny, slice of life with things happening.
Long-distance running made me run out (pun intended) of these audiobooks. Also, it's important to have take-away, characters that you can relate to, look up to. 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.
As Kai Wrenbury I can scratch this itch, create what I miss and share it with others. The pen name allows me to explore these ideas freely, without constraints.
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.
