I thought I recognized that name: Nylund also wrote some books for the Halo series which I enjoyed, although I was already a fan of the games.

I believe he was a staff writer for the Halo series in house as well, something like Marc Laidlaw at Valve, and the books emerged from internal storytelling written for the series. Very interesting stuff.

I also highly recommend his older books Pawn's Dream, Dry Water, and especially A Game Of Universe. They're available on Kindle and part of the Unlimited program so easy to check out.
