Wow! Good catch!
One fun thing with the Starfist series is catching all the little in-jokes and self-references that turn up. I just recently re-read Hangfire, and this time picked up on a pair I had missed previously. It had to do with two Vietnam-era military fiction novels written long time ago by our dear Starfist authors. These two books were described as "classics" and were in the contents of the the bookreaders that Pasquin, Dean and Claypoole carried with them to Havanagas. Claypoole commented that he had read both books several times.
Oh, yes, the two books were "The Soldier's Prize", a stand-alone novel written by Dan Cragg, and "Knives in the Night," the first book of the 6-book "Night Fighter" series. I am proud to say that I own a copy of both novels, although I have not read them as many times as Claypoole has.
