Started Mission Gamma: Cathedral last night and already got through 150 pages! It's really well done, but then, I'm a big fan of Martin & Mangels as writers. That said, I do think it took too long to get to the "point" when it's stated on the back cover very plainly. As ever, the station-board stuff grips my interest far more than the Gamma material, though I think this Gamma story might be the one I liked the most. (If the Vahni from Twilight are one of the best "alien" aliens.)
I'm also currently reading The Iron Kingdom: The Rise and Downfall of Prussia, 1600-1947. It's pretty good, if I find the author assumes a level of familiarity with mid-16th/17th century history I don't really have. As well, I am a bit frustrated by the stream of consciousness-esque style of the prose. While I'm generally a fan of non-linear storytelling. Having a chapter start in 1701, jumping ahead 23 years just to discuss a coronation not occurring and then jumping back to 1648, without clearly differentiating between the Wilhelms, Friedrichs, Friedrich Williams and Johannes, can get annoying.
