The Business, by Iain [no M] Banks
The Business recounts a slice of life in an up-and-coming executive in the eponymous organization. It's a fictional(?) millennia old organization devoted to making money and amassing power. Not particularly secretive, but they don't make waves. Given its age and the nature of compound interest, The Business is well-funded and thinks big. On the current business plan is to find a modestly sized country and acquire it for business purposes. Being a Banks novel, it's populated by oddballs, strange details, and crackling turns of phrase. Lots of Machiavellian plots within The Business as different executives jockey for benefits both business-related and personal (and many of them can barely distinguish the difference). I enjoyed it, but felt the loose ends got wrapped up much too rapidly at the end.
