Galaxy in Flames

This is the third in that Warhammer series I've been prattling on about these past few weeks. It's still a good series. The author of this installment, Ben Counter, doesn't seem as interested in the philosophical underpinnings of the whole story arc as the other writers involved, though.
What still impresses me is the way this group of four or five SF writers came together to plot out a multi-volume story, then divvied up the work. It comes off remarkably seamlessly.
