This is a strange book. Despite being number two in the series it is easy to get into. It jumps between areas of the world in self contained chapters(?) before moving to Mars. There seem to be large gaps between these locations, with things hinted to but not explained.
The Martian section, linked to War of the Worlds, has some obvious references such as red-shirted ensigns and a moon that is not a moon - it's a [spoiler!].
The ending is a little strange, too. I sort of want to know what happens next, but then again - do I?
Very good it places, naff in others; overall 3 stars
