content: For those who like space opera, this will be a bit of a disappointment. The first two installments of the Grand Tour opus have remarkably little science, and instead focus much more on political machinations in a world dominated by the USSR (Privateers) and then by a a global economic organization which seems to be the target of organized crime. Throw in a bit of sex, some greenhouse issues (explained in a very elementary way), and you have quick, light reading. Suitable for a beach or subway ride, perhaps an airplane trip? But not Bova at his best.
