The rising power of corporations has been a strong theme in SF since the '80s. It was a key element in cyberpunk and it's central to this novel. This isn't cyberpunk, though - cyber is largely irrelevant, certainly not a key theme or even an important part of the world building. Instead, Morgan extrapolates the trends of corporate power in the international political arena (in fairly conventional ways) and innovates by doing the same for corporate <i>internal</i> politics. These ideas are extreme and hopefully preposterous.
I found it to be a compelling read in that it's full of incident and yet, and yet...the actual plot develops slowly, is a little too predictable and our protagonist isn't a hero. Not even an anti-hero. Just an asshole. Which made it difficult to care - much like Kovac in the sequels to Altered Carbon.
