Wow. About 300 pages of set-up for 100 pages of action. The situation onboard the space station is explained over and over and over before we get there. Stationmaster Tillington is discussed ad nauseam and turns out to be a bit player when he finally appears. It's beyond me why more of this wasn't told from the kids' point of view, since they are at the heart of the story, actually living through the upheaval others repeatedly analyze.
