I think the bits where Garrick is interacting with Katherine are my favorites, but it's all good stuff. The only thing I'd recommend as a change in the post #25 letters segment is to include an actual name along with "Grandmother" for people like me who forget names so quickly we don't remember who that actually is. (Seto?)
For the other segment, I'm torn between wanting to suggest that Garrick as the top marksman discover and pass on the one-hit-mission-kill weak point of the crotch power junction on the battle pods and wondering what exactly would become of the pilots in the disabled if they were picked up as POWs... or worse, not picked up as POWs and left to drift until their sir and heat run out. Getting a bunch of them culture-shocked and turned this soon would be a (heh) giant-size butterfly to throw into the story, but then telling a new version of the tale is the point after all.
